Ha!
One of my friends when young (about 18 and very Scandinavian looking) was travelling back to Europe through Singapore and stayed at a nice hotel that a friend booked for her. When in the room and trying to sleep, she kept on getting phone calls from men, and she kept saying wrong number. Eventually, unable to get any sleep, she went down to the reception and asked what was going on and the concierge said,
"Sorry! I thought you were a prostitute!"
When she looked shocked he said,
"High priced prostitute!!"
LOL! That is too funny!
