Yesterday when I was doing my 90 day run, I noticed a big poster on display, apparently issued by the Ministry of the Interior. I can remember all the exact wording or clauses, but in general it authorizes immigration to deny a person entry into the Kingdom based on the appearance of the individual.
Some things that might see you being refused entry include.......
1. Long hair that's not neatly combed and/or appears to be untidy.
2. If you're wearing sandals of any kind, unless sandals are a part of your culture.
3. If you're wearing a sleeveless top without any undergarments. (I have a feeling this clause is aimed more at female visitors)
4. If you're wearing short pants that are very short. (again, I think they are referring to females)
5. If you have too many tattoos and/or piercings.
6. If anything about you or your appearance suggest you may be a hippy.
I do think some officials will take action based on the above, especially regarding some of the very "rough" looking visitors who show up, and maybe also with women in sleeveless tops without a bra. As westerners, most men are more than happy to catch a glimpse, but Thais are not the same, at least not the older generation Thais. A 50 year old Thai man does not want to see a stranger's breasts in a public place. Young Thais are of course changing as far as attitude is concerned, but the older ones see it as being rude and impolite.
I though the sandal clause a little extreme, but then again, I can't see it being enforced, and besides, very few Thais even know the location of different countries, let alone the culture in those countries. Hell, most don't even believe me when I tell them I come from South Africa. Africa is one country, so South Africa simply means the southern part of the country, and there are only black people living in that country called Africa.

On the plus side, maybe this new notice from the ministry will result in fewer noisy bikes.....lol.
