Pros
Bonuses aren't too hard to meet, lots of overtime, lots of autonomy. Get to work with folks in the local area, make relationships with local business people and frequent travelers. Get to help out people get the best value for their money, and in emergency situations (car accidents with totaled vehicle, for instance.) Advancement is very doable and not terribly difficult if you hit your numbers consistently, however some of that is out of your control, especially depending on which location you are assigned to. (Some areas are very busy, some only seasonally). Great for self-motivated individuals with initiative.
Cons
Little oversight and no support available for new hires. The job is not difficult, but it can be very stressful at times, especially when you find yourself at a small off-airport location with no location manager 90% of the time. Manpower seems to be an issue - there were periods, sometimes weeks at a time, when the entire city area was on a skeleton crew. Expect to be by yourself quite often if you aren't at a priority store location. Training was almost entirely done with online courses, while figuring things out as you went. Heavy emphasis on sales of course, but little actual know-how.
