1) You've order pizza/Chinese/bbq directly from a restaurant that delivers (not thru 3rd party service). Most people will tip the driver, but do you tip the driver expecting it to be shared with other workers at the restaurant or do you expect that the driver keeps the whole amount. Do you tip a flat amount you think "feels right" for the trip, or do you tip a percentage of the bill?
2) More interesting to me is to know about take-out. What do you think is proper? You order for pick up from a full service restaurant, not dominos, but a sit down restaurant that offers take out. Do you tip at all? If you do, how much do you tip?
