Recently, when I flew to visit family for the holidays, I used curbside check-in at the airport for the first time. The Skycap took my bags and then politely waited. It took me a few seconds to remember he wanted a tip… and then a few seconds more to realize I didn’t know what sort of tip was customary.

That of course got me thinking… then researching… and now we have this list below: The AnyNumberOfThings Tipping Guide. Think of it as a list of tips for giving tips.

I’ve tried to be as comprehensive as possible and include every situation you might ever encounter in modern life.

Common Tips

Waiter/Waitress-
I’d argue that 20% is the new standard. But if you’re old fashioned, then the old rules apply: 15% for adequate service; 20% for very good service; no less than 10% for poor service.

Taxi-
In most cities in the US, tipping is not mandatory. But that’s just the law. Of course you should tip. A minimum of $1-$2 for a short tip of only a few minutes, or a cross-town/few blocks trip. 15-20% for longer trips or driving to an especially congested or busy area of town.

Bartender-
As a former bartender myself, I can tell you that this is one case where the more generous you are, the more benefit you get (free drinks, quicker service, help with the DJ/ladies). If you’re going to be there a while, tip $2 for every drink and the bartender will definitely notice you. Otherwise: a minimum of 50 cents per soft drink, $1 per alcoholic drink (yes, including beer). And 15% to 20% of a running tab.

Hotel doorman-
$1 per bag for shlepping luggage; $1 per person for hailing a cab (minimum of $2)

Hotel bellhop-
$1 per bag for shlepping luggage. $2 minimum if you have just one bag.

Room Service-
Treat them like a waiter. 15% of total meal bill.

Parking valet or garage attendant-
$2 to bring your car to you. No tipping required when they take your car (but they might remember you and hustle for you if you do).

Skycap at airport-
$1 per bag if you check-in curbside. $2 per bag if bags are taken to check-in counter for you.

Pizza Delivery or any Food Delivery-
At least 2 dollars. More for larger bills ($30 and above) long trips or dangerous neighborhoods.

Less Common Tips

Coatroom attendant-
$1 per coat

Washroom attendant-
50 cents to $1

Concierge-
$5 for common task. $10 and up for a special effort scoring you those hard-to-get theatre tickets or “perks” of questionable legality.

Gas station attendant-
$1 to $2 for pumping gas, $5 for pumping gas and checking fluids

Barber/Hairdresser-
15% to 20%, minimum $1, for a haircut. For other services (shampoo, shave or manicure) tip $1 to $2.

Staff at coffee/food retailers with tip jars- No tip required. It’s completely optional. But I find spare change from the purchase or a spare dollar bill is perfectly appreciated.
