My wife and I were on a night bus enroute to Bangkok, Thailand. In our shared bag, I had a big knife I'd bought from a Hmong hilltribe smith in a refugee camp. At a police or military checkpoint, all male passengers had to get off so they could check for drugs, weapons, illegals, whatever.
They went through the bus and asked where the foreigner's bag was located. My Thai wife just pointed to the bag overhead. In is, they found the knife, which was somewhat like a Bowie, about 10" or so blade. Outside they confronted me about the "weapon". I explained to them in Thai that it was no big deal, just a knife I was bringing home. It didn't hurt that I had ID indicating that I was working with the Embassy. They finally stopped fussing and gave the knife to the bus stewardess for safekeeping.
The stewardess and passengers were a bit annoyed at the delay. She admonished me, saying she had announced prior to departure to check guns and weapons before leaving. I guess they would hide them up front, LOL.
The embarrassing part - or funny. What did they think of finding ladies underwear in my bag? My wife never let on that she knew me.
