Do you have a charger I could use?
I have a terrible headache. Can you bring something for it?
We can lend you a hair dryer.
You may use 100 and 110 volt appliances in your room.
If the appliance has a higher voltage, could you use it with a converter, please?
We'll bring one as soon as possible.
There is some shoeshine paper in the closet, sir.
There is a clothes (shoe) brush in the closet.
There are cigarette vending machines in the lobby and on the 10th floor.
Don't worry. I'll let the overnight staff know. They'll do it for you.
I don't know, but I'll do the best I can do for you.
Just let us know what you need, and if we can, we'll oblige.
If there is anything else we can do for you, please do not hesitate to dial "33".
