Tipping is customary in the US. When you travel to other countries, you follow their customs. Same here.
I think
Malcon10t and
ArchOwl said it right; tipping is customary here in the US, and when traveling to countries, you follow their customs, regardless of what your own may be. You may not like it, but good etiquette says that you should follow the customs of the country. I had a similar experience when I traveled to Egypt for a study abroad expedition. Although we had already purchased tickets to the various sites we were going through (pyramids, temples, etc.) it was still customary to hand the gentlemen who opened up the sites for us a few pounds. I didn't necessarily agree with it (as we had already purchased tickets), but it was customary in Egypt to do that and so we followed that custom. I later found out that most of those men make very little from the govt and those pounds they got from the tourists were a way to support their family and keep them in food. Obviously that is not the case here in the US, but it was still the custom and we followed it. Definitely didn't want to give the American tourist persona a bad image.
So I will be the first to say that stereotypes about who tips and who doesn't tip has led my DH to almost always tip 20% to make up for the Asians who don't tip well. Even if it's terrible service, he'll give at least 15% because he feels we have to prove that not all Asians are bad tippers. We're both Asian American, born and raised here, but I know Asian immigrants from other countries aren't used to tipping well or can be perceived to be low tippers. It may be changing now that more Asian immigrants with deep pockets are visiting the US, but we certainly feel sensitive to being judged based on appearances.
I have to admit but I had never heard about this stereotype of Asians being bad tippers until I went to college and understood the reason for it. My BFF from college was born and raised in Taiwan and came over at an older age with her family for better schooling opportunities. Her and her family never really ate out very much when they first came over or when they did, frequented Taiwanese establishments that were run by people who were "fresh of the boat" (her words, not mine.
) so tipping was not a huge deal for her. It wasn't until we became friends and ate out once a week (tired of dorm food and our own cooking
) that the subject of tipping came up and I had to explain to her the custom in the US and what was customarily expected. I never realized that most Asians who were either just visiting or were recently transplanted never knew to tip because it was always included in the price of the meal in Taiwan. Learn something new everyday! I am glad to know this now as my next overseas trip will be to Taiwan and Cambodia and I know what the local customs are.
That being said, I customarily tip 15%-18% at table service restaurants. Etiquette used to suggest 15% (my dad has a little card that gives the tip amounts per dollar amount that he acquired back before I was born
) but now with the cost of living going up (and inflation) I believe the new suggested percentage is 18%. Just be aware of this when you travel to the States, and you shouldn't have a problem.
