Add to this various "surcharges" and other mandatory fees added for this or that (my favorite: mandatory "resort fees" for hotels - seriously why is that not just rolled into the price of the stay?), and the service industry in the US has a serious price transparency crisis. It is quite literally impossible to predict the final cost of service, so as a rule of thumb I have come to generally expect to be out of pocket about 50% - 80% more than the listed price.
Any other country would call this fraud.
