Do you tip for take out that you pick-up yourself?
There's that infamous line for tip on the credit card slip, and I feel guilty if I don't put something there. I'm a generous tipper for table service, but never sure about take out. Is someone dependent on that to live?
And then, there's the opposite - food delivery. Do all have a delivery charge? I know the driver only gets a portion. Is your tip based on the bill, or per trip?
