Once -approximately 20 years ago - I went to Mae Sai in the North to do a visa turn around and when I came back I was tempting to Thailand I received a stand for 2 months when after 2 months I went out again to get a new stamp I was berated for having a two-month stamp which had nothing to do with me but was the mistake of the idiots who stamped me in
it has always been like this, 30 years or more....even at the consulates Never Smile when you arrive even through the FasTrak Lane they look at you like you're a criminal trying to sneak in....Its the most unwelcoming country in Asia they should all go for attitude training in Singapore and Malaysia
