Pros
You get paid to embody a goofy character and bring people food. Nearly every table is celebrating something, so they are typically in a good mood. You have the freedom to interact with guests as you see fit, within reason. If you are an extrovert and don't let standard retail grievances get under your skin, the work itself is easy (unless it's slammed.) The longer you work there, the more the staff feels like family. The building is rich in history (it was the first schoolhouse in the area) and everyone that grew up in Dallas knows what MTM is and has some memory of eating there as a kid and can tell you who waited on them 20 years ago. I love that I am part of so many childhood memories.
Cons
It's a 100+ year old building and the interior decor is about 50 years old. It is not well maintained. The GM is a man you either get along with (like me) or you don't. Same with dealing with guests- you love being on the sales floor or you don't understand why anyone keeps coming back to work. Employees either stay at MTM for a week, or for 5+ years. There is no in between. I'm in an online moms group and guests say the same thing- moms either rave and tell everyone to go there or they tell them to run for the hills.
