glenn, how many people are using cash to pay at upscale places? i've probably used cash to pay for a meal once in my last 300 meals. additionally, if i do pay cash, and the bill is say 66.21, i'll probably just leave 80 on the table and head out the door. are these pennies really so much a problem? you say yourself it's not adding up to much. seems you've got the solution sussed. and "don't overcharge your customers" isn't a vague generality, nor is it, i think, meant to be a solution to this huge problem that the industry is faced with. it's just common sense and good business. if they don't have that going for them, they're probably beyond help.
