Tipping in the United States
In the US, tipping 15-20% at restaurants and bars is a cultural norm because servers are paid low base wages and rely on tips. Tip taxi and rideshare drivers around 15%, hotel housekeeping a few dollars per night, and bartenders about $1-2 per drink. Tip screens now appear almost everywhere, but for full table service 18-20% is the safe range. Leaving nothing is read as a complaint, not thrift.
