At the risk of sounding like a grammar Nazi, it irks (and amuses) me every time when I see Tinglish. Why? Because even in their less-than-perfect constructions, you get what they are trying to say, albeit not right away.
Wanna know if you're well-versed in Tinglish? Here's a fun quiz to find out whether you can decipher Thai-style English. Just pick what you think these examples (with some context in the brackets) are trying to convey in normal English. I took them from real-life signs at various places but decided not to use the pictures to make this quiz more of a challenge. The answers are below. No cheating.
ANSWERS:
The more you answer B, the better you can speak Tinglish.
