Mr . Lee , all ready to check out ? We ’ Ve already prepared your bill , and housekeeping has done a quick check of the room . How will you be paying ?   I ’ d like to use my Master Card , if I could . Hey , wait a minute ! This is a bit more than I expected . Why is it so high ?   The bill is itemized , so take some time to look through it and make sure we ’ Ve charged you for the correct services . Most of your extra charges were for phone calls and room service .
