Except for the "Denny's server is probably poor" part, I agree.
So you think a 40 year old woman working the night shift at a Dennys is doing so for extra spending cash on the side?
No one mentioned 40 year ladies working night shift,. Unless every employee working at Denny's are 40 year old women on night shift, then you don't have a point. There exist one "40 year old woman working a crappy shift" for most jobs. Depending on how you define "poor", not EVERYONE working at a minimum wage job is poor.
