As vi13co said, it really depends on the location and the type of customers each store gets. Typically, all places would get pretty busy during the summer time cause 1) School's out, 2) Employees want to go on vacation, 3) Tourists. It also depends on what type of availability the store is looking for. The age thing is only a problem because if you're in highschool, you can't work past 9 on schoolnights or something like that. I worked at a downtown location when I was still in high school, and I had a few coworkers who were as well, so as long as you're 16 and can prove that you're mature enough to handle the job, I think you're good to go. Technically they are "always hiring" because there's always people coming and going, I think my ex-manager said that the average turnover rate was about 6 months. And yeah, make sure you get the manager's name and number so that you can call to follow up.
