Pros
Flexible part time hours. low commitment requirement for entry level positions (just show up on time). Slower and smaller scale retail store that does not get heavy traffic often. A slower paced retail job more focused on customer support and an eye for detail rather than your actions-per-minute. Smaller team sizes ensures that you'll not get lost and forgotten, and you'll learn about everyone you work with pretty well in just a month. Mistakes happen, no one is expected to know everything, and it is difficult to get fired (unless you're not showing up/literally doing nothing consistently). Whether your a manager or not, the flexibility can make it worth it if you are doing part time, or even full time. It is very straight forward requesting time off or establishing your availability, even if you can only work a day or two out of the week.
Cons
It's retail, like all retail jobs, you deal with the nasty creatures that are the common consumer. So the occasional nasty customer, dealing with thieves/homeless, and cleaning up after self-entitled people who tear through your store, is the gist of it. Same basic retail experience. Besides that, the management above your store manager will be out of touch and have obtuse objectives and sporadic enforcement of their own rules and goals. Constantly understaffed, as a consequence of being flexible with part-time employees. Being a slower store does benefit this issue, though doesn't entirely make up for it. Full time and part-time managers tend to be stuck with the most responsibility and for not a very manager-like pay. Managing the sales employees can feel like herding sheep. A constant deluge of tasks only a manager can accomplish, paired with needing to approve every little action for part-time sales and a constant understaffing issue means you'll never get anything done. Really can make or break the experience if you can't get along/in sync with your coworkers and managers, (I personally like my store manager, experiences can vary depending on location).
