It's an outside job so you have to deal with sweltering heat and sometimes serious cold in the early spring. shifts are typically less than 8 hours, usually 6.5 hours. Shifts are often shortened/cancelled due to weather. No breaks. Customers can be rude and entitled when you enforce the rules. Training is very rushed; you have to learn a lot on your own, and different supervisors will tell you different things. You might have to cover for a stand you've never worked at, and have to learn on the spot with a line of customers in front of you. You might have to work with teens who may or may not pull their weight. You may also have to work with adults who wander off for hours and leave you by yourself during the busiest time of your shift. The 1st floor is much more crowded than the 4th floor, and the customers are ruder as well. If you wanted variety in where you're placed each shift, you probably wont find it. In Ohio, if you're 19 or older you'll almost exclusively be selling alcohol, since 18 year olds and minors legally can't.
Supervisors can be hard to find, and you often have to wait for them to finish making their rounds at all the stands. Same goes for managers. I had a card I needed to use to sign in to the POS. It didn't work all season and the manager could never find the time to get me a new one.
