Restaurants: 15-20% standard, with 20% for excellent service if you dont want dirty looks from your server. Some places auto-add 20% for parties of 6+ so check your check.

Bars: $1 per drink minimum. Tip when you order if youre running a tab.

Cabs: 10-20%. Uber/lyft same deal. Cash for yellow cabs is better cause the credit card companies take their cut.

Hotels: $2-5 per night for housekeeping. $1-2 per bag if the bellhop actually helps you. Doormen get $2-5 for hailing cabs but only if they actually get you one.

Here's the thing - service workers here live off tips. It's not europe where they get real wages. Dont be that tourist.
