I don't want to sound naive, but has anyone ever heard of any Thai guy ever robbing a farang in his hotel room with a knife? I tend to doubt--at least with the kinds of guys we take to our rooms--that this happens. Even if a guy produced a knife, I think I would call his bluff and he would leave quickly, with nothing. I know--easy for me to talk--but if this is just a 1 in 100,000 chance, then I'm not worrying about losing some cash.
