knox is one of the most ignorant dumb asses i have come across on this site. As many mentioned before it is customary for them to have the guy come out and he is rewarded with a tip, which can add up to more than his salary from his employer, you think these workers would prefer it if everyone would walk in and they no longer get these tips that earn them more than their official salary? Stop being such a self-centered ignoramus and expect every culture to suit itself to your ideals of what is right or wrong.
