Avantages
You meet new people who are just trying to make a little money just like yourself. The training is straightforward and usually whoever is training you is genuinely nice.
Inconvénients
As a cashier, they will actually time how fast you ring customers up regardless of how many shopping carts and items that the customers have. Depending on who's supervising, you can get a very rude remark, telling you to pick up the pace. If you're setup at a register near the clothes area, be prepared to waste time trying to ring up clothes (some have price tags missing). Even for part-time, the work schedule is not as flexible. It can get very boring on a slow day and on a busy day it can get extremely hectic but that's typical with most retail stores.
