Dave and Buster's is normally quiet during the work week, unless there's a sports game playing. Most of the staff are nice and easy to talk with, the guests are generally nice as well. However, if you plan to do anything on the weekends, you'll most likely be working at D&B, as those are the busiest days. If you do plan on taking time off, it's paramount that you inform your managers well ahead of time so they will know not to add you to the clock. Sometimes they are forgetful, so be sure to remind them repeatedly.
As for my job, I will say there is some joy in making sure the dining areas are kept clean, though picking up used dishes all the time can make you feel disgusted a bit.
