I tip for good service never below 15% with exception ofvery poor service, Its usually around 20% plus. I know what its like to work in food service. I also tip my barber, bell hops, sky caps, hunting guides, and anyone else I think needs to be. Murray and Mayfield are a horrible place for servers to work considering the high concentration of elderly who feel like 50 cents is an adeqaute tip. I had the pleasure of dining at a fantastic eatery in Paducah during the Quilt show where a plates average north 30 dollars a person and I witnessed a group of 8 older quilters leave 5 dollars. The little girl busted her hind serving her tables including ours. No glass ever went empty. I felt so bad for her.
