Great post, Jordan. Sadly, most people believe that because they're the ones who technically pay waiters (by leaving a tip) that they're entitled to treat them however they please. I once had a guy who wouldn't look me in the eye as I was taking his order, and who told me that if his food wasn't ready within ten minutes, he would leave. When I told him that he could save himself ten minutes and leave right now, he tried to get me fired. So, basically, he can talk to me any way he likes, but if I give it back to him it's grounds for termination. Most people just don't have manners any more.
In response to the actual article, I think that some of the rules are totally true, while others are totally patronizing. The guy who wrote it is obviously new to the restaurant business--he makes his ignorance quite clear by listing things that are either a) common knowledge or b) not done in any restaurant.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
