Tipping in America - Telegraph Denise Key, York, writes I will be travelling to the US for the first time this year, and have heard confusing stories about norms and expectations regarding tipping. It would be helpful to have a basic idea of circumstances where tipping is obligatory/expected, and when it is optional, and also the amount I should give. Douglas Rogers, New York expert, replies Ah, the eternal "tipping in America" question. It can be confusing, and even Americans don't always agree. Recall the opening scene of Reservoir Dogs? Here are the basics. Wait-staff rely on tips in the US, and the standard tip in a restaurant is 15-20 per cent. If the service is average tip 15 per cent - or less. But the theory is that service will be good because waiters depend on tips. In a bar, a dollar a drink is standard. That said, if you're settling in for a few cocktails it's worth it to slip the barkeep $5-$10 upfront. Guaranteed you will be well taken care of. Taxi cabs in New York have an automated debit/credit card system with three tip options: 15 per cent, 20 per cent, 25 per cent (the latter amount is outrageous!). For a normal cab ride, 15 per cent is fine - and if the ride is short, less than that. Then there's the bellboy delivering bags to your hotel room: a dollar or two will suffice, although if you are staying a few days, it may be worth it to tip $5-$10 up front. They will remember you. Hotel maids are rarely seen, but leaving $3-$5 in the room when you check out is courteous - and they probably need it more.
