I have only been twice at two different locations and there were no servers. Don't remember the cost but it didn't break the bank.
I am a health conscious person who watches what he eats and exercises almost every day. I am in great health with good blood pressure and I take no medicines.
That being said, a few times a year I treat myself to a nice juicy burger and fries. I don't feel guilty because I know it is not part of my regular eating lifestyle.
Had to get that off my chest, I'll step off the soap box now.
