I have what may be a stupid question or even a pointless one. But here goes anyway. For high end dining (Charlie Trotters, French Laundry, Inn at Little Washington, etc) is it in some way poor manners (not sure if that's the exact word I am looking for) to pay for your meal in cash? I honestly have never seen someone pay with cash at a place like this and haven't paid with cash myself.
Sometimes I'd rather just pay cash instead of putting the meal on the credit card, but wasn't sure if in some way it would be frowned upon. I would think cash would be preferred so the restautant wouldn't have to pay the credit card fee, but at the same time, cash is considered "dirty" and full of germs by many.
What are your opinions?
