Tips and service charges are usually not automatically added to a bill. If service is satisfactory, customers generally give waitstaff 15%–20% of the total bill. Hairdressers, taxi drivers, and other service specialists receive 10%–20%. Bellhops, doormen, and porters at airports and railway stations are generally tipped $1–$2 for each item of luggage.
When visiting coffeehouses, throw your change or $1 into the tip jar on the counter—like waiters, baristas depend on tips to supplement their wages.
