I read an article on MSN today about the extra charges that US cell phone companies charge. It says not all of the charges are government imposed, such as taxes etc
a lot of them are charged by the cell phone company to pass on the cost of doing business. This is done a lot by car rental companies as they charge for everything to pass on the renter. Airport fees, auto registration fees and there is a long list of charges that have nothing to do with government taxes. Imagine if every supplier did the same thing? Charge for bagging, electricity, checkers, parking, after hours charge. They could have field day. but as has already been said here the public would not except (cost not including VAT) advertising of prices on clothing for example.
A lot of UK tourists feel they are being ripped off in their change in the US when they don't know about sales tax not being included in the posted price on items for sale.
