15 percent to 20 percent of the
total bill, closer to the latter if the service is good. Exception: If a
wine steward, or sommelier, picks and serves the wine, the wait staff's
tip should be 15 to 20 percent of the food bill only. Watch out: Some
restaurants add a gratuity of 18 percent or more to a tab for large
parties; look before adding a tip.
Concierges
Anywhere between $5 and $10,
depending on the service provided (i.e., dinner reservations, show
tickets).
Door attendants
$1-$2 per bag, and $1-$3 for
calling a cab.
Room service
15 percent of bill, unless
gratuity already is part of the bill.
