Only fragrant fruits, please

Checking into my hotel in Semarang this afternoon, I noticed a small sign at the reception counter informing guests that cigarettes and "strong odors" are not allowed in the lobby. I figured maybe some guests had a BO problem, but when I got to my room, I saw a sign with the following:

Dear Guest,
The Hotel has a policy of not permitting the following:
* Durian fruit is not allowed on the premises.
* You are not permitted to remove the mattress from the bed and place on the floor and other furnitures moving is prohibited.
* Smoking in Non-Smoking rooms is not permitted.

I guess the hotel has had its fair share of interesting incidents in the past.
