If you are not happy with the service from this waitress, contact the Manager of the restaurant and share with them your experience. There are endless reasons why the waitress, in that moment, responded in this manner and unless you are prepared to ask her directly, any assumption or speculation is counterproductive. What you saw as b*tchy, could have been someone who was tired, unwell, under personal or financial pressure or miserable in their job.
The possibilities are many and while customer service is naturally expected in a dining establishment, some people get caught up in their own crap and inadvertently or intentionally take it out on other people.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
