Pros
The retirement is really good.
Cons
You will die before you see your retirement. GMs get zero respect, are micromanaged, and have unrealistic standards thrust upon them by completely out of touch area managers, and corporate mouth breathers who have no idea how their stores actually operate. You're expected to be on the clock 24 hours a day, and to cover any shift that needs it. Rain, shine, snow, blizzards, hurricanes - these stores never close, your employees will contact you at all hours of the day or night, whether you are on vacation or not, whether you set boundaries or not.
