I got done 1 time at chong chom border crossing with 1 too many cartons of cigarettes I bought at the duty free in the casino.
I honestly didnt think anything of it, duty free naturally sold them to me no problem.
Got to the thai side and a totally plainclothes thai dude with a dust mask & sunglasses on grabbed me by my arm, hard, and tried to drag me off. I thought it was some retard tout trying to get me to buy something or some shit so I did what any human would of done after he wouldn't let me go:
I shoved that fucker so hard he fell on his ass.
Whelp turns out he was a customs "spy" and identification isn't required whilst assaulting foreigners. He was not pleased.
I sat on the side of the road in bracelets for 5 hours under armed army guard refusing to pay the, wait for it, 100,000 baht fine for the "cigarettes" but nobody spoke english so they got a motorbike taxi guy to explain to me that:
this is tai lan you no tai you mus pay this is tai lan you do no good you no pay you go to jail long time you do bad you no good
Ended up paying 14,000 baht after being taken to the "big boss" with about 8 other thai men in 2 toyota trucks taking my picture & shit the whole way.
Over 1 carton of cigarettes and a fuckhead who thought it would be clever to grab onto people without identification or anyway of making it known that they were, infact, customs people.
Fuck these idiots.
