Thailand
At restaurants
Ordering at street stalls, spice levels, and paying at the end.
Do you tip in Thailand?
Optional, and never expected at street level. Leaving the coins from your change is the usual gesture.
Is the street food safe, and is there any way to tell?
There is an actual certification to look for — Clean Food Good Taste, run by the Ministry of Public Health. It puts a checkable mark on what is otherwise a judgement call.
Do I eat Thai food with chopsticks?
No — spoon and fork, and the spoon is the one that goes in your mouth. Reaching for chopsticks is the most common visitor misfire in the region.
