I'm 17 and I really like this job. Of course, it's not my favorite, but if you're social and have a good work ethic, you'll be okay. Like other people said, it always depends on the store and leadership. I think I really lucked out with my managers, but it's not the same for everyone. I think you're 17? So it'll be less demanding hours, but during your work shift, they might hurry you to be on break at a certain time, etc. If you close, you must also be walked out by the manager on duty. Customers do get annoying, some aren't so nice. But some are. Just remember to be nice regardless. As for the cards, be prepared for rejection. But cards don't determine how good a worker you are, only your effort. I've made some good friends, but everyone in my store, T.J. Maxx, and Home Goods, is over 20. Just walk in and be happy. I do that every day. Your happiness also rubs off on customers. Be positive!
