Having lived in other countries, the US habit of 'nickel and diming' every sale with taxes and fees that aren't fully announced until payment is one of the most annoying cultural failings. Even governments do it; I recently bought a tree removal permit and my city tacked on a ~15% 'technology fee'. This after I wasted a good hour dealing with the absolutely awful website for the permit application - having to enter the same information on multiple pages by hand, broken address lookup, ugliest imaginable design and layout.
