Why Do People In Charge Make Others Do Ridiculous Things?

Why do people that are in charge of a situation make decisions that make others uncomfortable? Ridiculousness may be in YOUR comfort zone, but not in others. Take seat assignments at weddings, for example. So you want to split people up that all know each other so everyone can sit by people they don't know and make new friends? This isn't kindergarten. We don't want to make new friends that we will never see again. Especially your whiskey-drinking, New York Times-reading future in-law snobs. ARE YOU SITTING BY A BUNCH OF STRANGERS? No! You are sitting by people you know so that you can watch the rest of us as we attempt conversation with people we don't know and will never see again. Weird. As a guest at a wedding, I want to sit by my friends and family. I like my family and friends. I spent time and money to come to your wedding, I gave you a nice gift, at least let me sit and eat with people that I enjoy being with. I think "I'm going to split everyone up so that they meet new people" is code for "I don't want to take the time to prepare a seating chart so I am just randomly going to put people anywhere". That's what I think. 

Why are car mechanics so possessive?

Why do car mechanics think they own your car? I went to the car dealer today to get my oil changed. I will admit, I was a little over the 3000 recommended mileage since my last oil change. I've been busy. My car gets very good care. I get my oil changed on a regular basis. So what, I was a little over this time. When the service advisor put me into the computer and saw that I was over 3000 miles, he peppered me with all kinds of questions. "Have you been going somewhere else for your oil changes?" "Why haven't we seen you lately?"  I felt like I was talking to Tony from the Seinfeld episode, "The Bottle Deposit". I started to get worried. Was he going to turn me in? Was he going to kidnap my car like Tony did to Jerry's car? So what if I had taken my car somewhere else for an oil change? I did confess that a tire company was now rotating my tires. Why should I feel guilty about that? Geez! It's not that serious!
