It is all relative though. While you may not pay more, in certain merchandise situations, you can certainly pay less if you know what your doing, thus, you are often paying more than you would if it was tip based. Americans know about the tip, understand the tip and seem to overall have no problem with the tip based payment system. I am curious how the non-tip transplants like zoolook or others who have lived in the states for an extended time now think of it.
