Passage One Questions 46 to 50 are based oil the following passage．
As a person who writes about food and drink for a living。I couldn’t tell you the first thing aboutBill Perry or whether the beers he sells are that great．But I can tell you that I like this guy．That’sbecause he plans to ban tipping in favor of paying his servers an actual living wage
I hate tipping．
I hate it because it’s an obligation disguised as an option．I hate it for the post—dinner math it requires of me．But mostly．I hate tipping because I believe l would be in a better place if pay decisionsregarding employees were simply left up to their employers，as is the custom in virtually every otherindustry．
Most of you probably think that you hate tipping，too．Research suggests otherwise．You actuallylove tipping!You like to feel that you have a voice in how much money your server makes．No matterhow the math works out，you persistently view restaurants with voluntary tipping systems as being abetter value，which makes it extremely difficult for restaurants and bars to do away with the tippingsystem．
One argument that you tend to hear a lot from the pr0—tipping crowd seems logical enough：theservice is better when waiters depend on tips，presumably because they see a benefit to successfullyveiling their contempt for you．Well．if this were true．we would all be slipping a few l00-dollar bills toour doctors on-the way out their doors，too．But as it turns out，waiters see only a tiny bump in tipswhen they do an exceptional job compared to a passable one．Waiters，keen observers of humanity thatthey are．are catching on to this；in one poll，a full 30％said they didn’t believe the job they did hadany impact on the tips they received．
So come on，folks：get on board with ditching the outdated tip system．Pay a little more upfrontfor your beer or burger．Support Bill Perry’s pub，and any other bar or restaurant that doesn’t ask youto do drunken math．
