You find a bag of groceries in a cart in a store parking lot do take it, leave it, or return it to the store?

Furthermore, eating in the store can create spills and unsanitary conditions that make shopping less enjoyable for other customers. While shopping carts are in use they become part of customers' personal space. Polite shoppers will respect that space and not remove items from another shopper's cart, nor will they add an item to someone's cart as retribution for rude behavior - another rude act does not correct someone else's actions.

It is also polite to avoid moving another individual's cart; if the cart is blocking your way, ask politely for the shopper to move. Many grocery stores offer product samples to tempt customers into additional purchases. If you want to try a sample, feel free to do so, but avoid taking multiple samples or using sample stations as a buffet line.

This prevents other customers who are interested in the product from trying it themselves and abuses the store's generosity in providing samples. Similarly, avoid using samples as snack time for children shopping with you. A cell phone may be convenient for checking on a missing ingredient or verifying a grocery list, but avoid having protracted, personal conversations in a grocery store, particularly in the check out line where other customers and the cashier are forced to listen to your conversation.

Instead, return calls after you have finished your shopping. Before entering a check out line, double check your grocery list or review the items in your cart to ensure you have everything you need. If you discover a missing item once you are in line, leave the line completely to get the item rather than dashing off and making other patrons wait.

When you return to the line, your proper position is at the end, not at the same place where you left. If you change your mind about an item, either reshelve the item yourself or hand it to the cashier and let them know you no longer want it. Above all, avoid placing items - especially perishable groceries - on improper shelves where they clutter up space, obscure other items, and are unavailable for shoppers looking for the same item in the correct area.

If you have multiple items you no longer want to purchase, reshelve them rather than handing many things to the cashier. Many grocery stores offer express lines for customers with just a few items. The listed totals, which may range from 5 to 20 items, are for the total number of items in a shopper's cart, which includes multiples of the same item.

If you have more than the appropriate number of items, find a different line to check out. Similarly, respect check out lines that require particular methods of payment, such as cash only lines. When placing your groceries on the conveyor belt, keep them grouped together and easy for the cashier to scan.

This will help the line move more quickly and allow your groceries to be bagged more easily. When all your items are on the conveyor, place the separator bar down so the next customer can begin to unload their cart and the cashier knows where each order stops. It is no surprise that after the cashier scans all your groceries you will be expected to pay for them.

While waiting in line, organize any coupons (double checking for expiration dates) and prepare your method of payment, whether that is writing out part of a check, finding the right credit or debit card, or getting out your wallet to pay cash. This will help the check out process move more efficiently and conveniently for everyone in line. With more and more people opting for debit cards to pay for groceries, it is polite to respect other shoppers' privacy while in the check out line.

Avoid standing too close to other shoppers as they pay for their groceries, and avert your eyes from electronic keypads and grocery totals. Stores may eliminate baggers in an attempt to keep costs low, and if you do not have a bagger take the initiative to bag your own groceries rather than force the cashier to perform two jobs. This is especially helpful and polite if you bring your own reusable bags.

At the very least, move filled bags from the bagging area back into your cart instead of requiring the cashier to walk away from their station solely for your convenience. Simple common courtesy is often overlooked in a grocery store, but making eye contact and offering a genuine thank you to anyone who offers you a service is always polite and appropriate. Thank your cashier, the deli clerk who gets your cold cut order, the baker who gives your children a sample cookie, and anyone else whom you interact with in the store.

After you've completed your shopping and your groceries are safely stowed in your car, be polite to the next shopper by returning your cart to a parking lot corral or directly to the store. Unattended carts cause significant damage to cars in grocery store parking lots, and simply shoving a cart onto a nearby curb still blocks parking spaces for future shoppers. To be even more polite, take an abandoned cart into the store with you every time you do your shopping.

No matter how polite you try to be, there will always be other customers who are unaware of the proper grocery store etiquette. Instead of reacting in a rude way, be patient and polite and you will find grocery shopping to be less stressful and more enjoyable.
