Pros
Interacting with customers and fellow game masters is pretty great. If you're a high schooler looking for a job on Saturdays and Sundays, it would probably be nice for you.
Cons
The place pays barely above minimum wage, yet the owners act like the couple dollars they pay extra makes them basically Jesus. You can get more money down the street at McDonalds or Walmart, but the company doesn't seem to want to acknowledge that. For that crappy pay, you get "scheduled" for a ton of hours a week, but you may only work one or two shifts since all shifts are considered "On Call", which means sitting at home completely unpaid, yet unable to do anything else because you can be called in up to an hour before or after your scheduled shift, and expected to be there in an hour, sometimes less. If a day you're scheduled to work is slow, you might never get called. If there's a slow week, you may not get to work at all the whole week, so do not expect any kind of stability with this company. Despite this, the employees are expected to keep the place clean and fix any broken props without any kind of formal training (I guess you're lucky if you learned any of it before coming here), but the managers are not allowed to keep you on clock much outside the times of scheduled games, so it's never really stated when this cleaning and maintenance was supposed to happen. The owners also promise all these wonderful bonuses if you meet sales goals of selling the security camera quality pictures of games to customers, which doesn't help the people who aren't great at sales, and the quality is pretty bad regardless. The bonuses supposedly get bigger if your location manages to hit certain goals with reviews on google, but the owners put unfair barriers to hitting those review goals so no location ever gets them. The owners play favorites badly. They'll listen only to what they want to hear. They'll skew statistics to make their precious Sherlock locations (The "Sister company" to Mastermind) in Kentucky look better and constantly knock down the Masterminds, despite some Mastermind locations doing more business.
