Pros
Decent seasonal work Some interesting customers, which can be pleasant It's only on weekends which is great if you're a full time student during the week and just need an extra pay check. Most of the other people working there are very nice.
Cons
Poor management for the most part. Most of the supervisors don't understand how the booths work, but will keep coming up with very asinine and inefficient ways to run the booths and then blame you when it's not working. They'll also become upset if you try to fix it yourself, regardless of the results. It can get incredibly hot. Do not underestimate the sun. At some booths you get 15 minute lunch breaks. Which is either just enough to catch your breath or down a snack assuming your brought one. Do not expect to be able to buy food there in that time, the lines can be bad.
