"I’ve worked as a maintenance worker at a concert venue for a few summers and have bumped into several celebrities, but Carrie Underwood is the one who sticks out because of how demanding she always was. She refused to use a toilet if someone else had sat on the seat before her — cleaning them was never good enough, so we had to buy new toilet seats every time she came. Considering how much we already had to fix, the last thing we wanted to do was pointlessly replace perfectly good toilet seats. In contrast, Reba McEntire would always eat lunch with the staff and was always super chill."
