You face your first dilemma as soon as you land at the airport – the taxi ride. Taxi drivers generally do expect tips, but rather than there being a precise amount, people round up the far or just tell the driver to keep the change.
Your next encounter is with the hotel porter and you know he’s expecting a tip, but the problem is trying to figure out how much. It seems that in many countries round the world $1 per bag would be an appropriate amount.
