If you have to stay later make sure you are getting paid, if you aren't you need to say something. No offence, but being a hostess isn't really a difficult or demanding job so you really can't expect the pay to be that much for a position like that. If you quit then what would you do for money.
Yes, people usually give a 2 week notice but since you've only worked 3 shifts, they might decide to just let you go then and there. Or you can just straight up quit and not come in anymore since I doubt you'll be putting this down on your resume.
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. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
