That's dreadful. At the risk of sounding like a brown-noser, I suggest the OTHER T.I.T. acronym: trust in Tod. Self deprecation notwithstanding, neither I nor any of my friends who have sought advice here have been steered wrong. See what wizened widom will get you. Good luck!
I had a stamp in last year in which I was required to leave the Kingdom.... a full week before I even arrived. It was one of the rare moments in immigration at Suvarnabhumi where I have seen any officer crack a smile. Of course, I did NOT take it back to the fellow who had stamped it, but found a boss.
On the brighter side... In and out of Mae Nam immigration in under 20 minutes on Samui. One of the IOs actually came outside to fetch me while I was having a cigarette. "Sir? Finish!"
