If the FA tips and I don't, does not mean I am cheap... just means I don't believe in tipping van drivers that's all...

I have tipped about 25% at restaurants and not on a lousy $10 bill, but on $100 bills for excellent food and outstanding service... I know I am not cheap... just don't believe Van drivers or Starbucks workers or any other service where they are paid propper wages requires a tip...

in the end for me it's just a matter of principal
