Pros
They will hire for 40 hours a week which many other jobs in this category won't. If you can work the morning shifts the time can go quickly and you can get to create a rapport with the regular customers.
Cons
Abusive customers especially drunken patrons at night that can't handle that last call is 2 AM. Expected to upsell every customer and shake them down to contribute to the donation jar so that your district manager can win a vacation. Regular customers become irritated if they come in everyday, buy the same thing, and have to listen to a sales pitch every time. Upper management policy and store level reality are two separate worlds. Management wants you to keep hot dog rollers and hot sandwich dispensers full, and coffee pots full all night long. If you did these things you would waste so much inventory that the district manager would freak and demand to know why there is so much inventory loss.
