Picking the right percentage
US convention: 20% for good sit-down service, 15% for adequate service or a modest counter tip, and 25% when someone genuinely made the meal better. On a $100 bill the whole spread from 15% to 25% is $10.00, which is worth keeping in mind when the payment screen makes the choice feel bigger than it is. For delivery, tip on the food total and lean higher in bad weather; for takeout, tipping is appreciated but genuinely optional.
