I studied Thai for 6 months and thought I could at least order food. So I tried ordering in Thai. Ordered pad krapao moo sab not spicy but got pad thai shrimp very spicy. Ordered khao man gai but got khao moo daeng. Every time I got the wrong food. The shop owner just smiled and brought the food over. I did not know what to say so just ate it anyway. Later a Thai friend told me my tones were wrong. Moo for pork and muu for village sound different. Thai tones are really so difficult.
