Maybe possible in china when u pay with credit card in bigger establishments.
Sometime the decription of the bill (upon request) will state "hotel expenses, meals, drinks, rooms, etc.
In HK, if you are talking about hotel gals, walk up or brothels, I suggest you print your own receipt and stamp. The WGs will be ok to stamp their puss lips on it...
In most stationery shops in HK, u can get those ready printed receipt.
Write down some beautiful chinese characters and put your ugly signature on it (assume ur boss dont understand chinese).
Once when i visited a SN/SPA during biz trip in SEA, the bill printed "meals" in local language and the letterhead of the bill was a hotel name. Hell, it save lots of $$$
dont quote me!!!!!!!!
