Pros
If you need hours you can usually get them, relaxed dress code and atmosphere, simple but satisfying work. Coworkers tend to be excellent people. Pay is better than most retail jobs of the same level and more opportunity for advancement.
Cons
If you work as a delivery driver you will be screwed over on a regular basis. They don't have much in the way of established rules for paperwork. Management's culture seems to be full of people with little respect for the employees, safety, or health standards. Complain about any of the above and you're likely not going to find any support from upper management, which is who you have to contact since they have no HR department that I know of, and you're likely to find yourself soon out of work for your trouble. If your schedule doesn't work with what they need expect retaliation from management.
