Queen Sirikit quoted 50000 per eye when I inquired a year ago. They admitted that this was the special Farang charge. 20000 would be standard for government hospitals in Thailand. I ended up having it done at a private hospital in Vietnam for 20000 Baht.
That was true 20 years ago, they have diversified a lot since. Sure, there are still a lot of Thái products, but also a lot from Vietnam, China, Malaysia, and more and more locally made stuff.
Thais are not good with numbers. You buy two items in a shop. One costs ten Baht, the other 5 Baht, they use a calculator to add that up. Give them a 20 Baht note, again the calculator to determine the change.
There is no prostitution in Thailand. It's a deeply devout "Buddhist country".
The former prime minister General Chavalit, the initiatior of the Tom Yam Kung crash, inspected Pattaya and couldn't find a single hooker.
