I ran across this today in another blog – cracked me up and scared me at the same time! This was written by a guy who worked at Wal-Mart for a while:
For example, I worked for three weeks in the Purcell Supercenter’s Tire and Lube Express. I changed hundreds of people’s oils. The top-side part. Changed their air filter, checked levels, tire pressure, etc and most importantly filled their engine with oil. I rotated and balanced hundreds of tires. I had no idea what I was doing. None. I couldn’t get a job sweeping the floor in a non-Walmart garage or tire shop. I was taught a series of steps that I performed over and over People that know me well know that I know nothing about cars or engines or tires. Nothing. Nothing. Nothing. So think about that the next time you drop off your keys and head inside to buy a new comforter.
