I'm terrible at tipping and this is the one thing I do know. But – It's next to impossible to get enough small bills to cover all the tipping you need to do on a vacation, between hotels and taxis, and other incidentals. ATMs typically spit out the local equivalent of USD$20s if you're lucky; US$100s if you're not. Who's going to make change for that? At home this is less of a problem because (a) I don't have as many things to tip for, and (b) I have had time to save up small bills for tipping. But when first thrust into a foreign country you need to be PREPARED.
