Oh I'm probably gonna catch he'll for this... I tip. I tip well. At a dine in establishment (not buffet), my standard tip is 20% of the bill in cash to the server. As service drops so do my tips. If I ever leave a tip less than 15% of the bill, I always leave a (nice) note to the server and speak with the manager of the establishment indicating why the tip was not as high as it could have been.
At a buffet establishment... I might tip 10% if they treat me like a king, but most of the time all that the tip will be, is the change to round the bill up to the next dollar... why should I tip when I get my own food, and my own drinks? All the hostess did was show me to a table and give me silverware...
I know, I'm an *******...
