One of the biggest challenges that comes with being a car salesman is downtime. This job is easily 75% sitting around trying to keep yourself awake and 25% running your ass off. Having too much semi-free time (I say semi-free because every salesperson worth his or her desk always has one eye on the lot) is one big reason why I got into writing blogs.
One of the most destructive forces in the world is a bored car salesperson.
You don't think so? Think about it. If you're bored at work, it usually means you're not doing anything. The same thing applies to us. The difference is, if you're bored, you're still getting paid. A bored salesperson is a broke salesperson.
So, because we're not doing much a lot of the time, each of us has something that they do to pass the time. I, for one, write blog posts. It allows me to keep my mind engaged while blowing off time. Some guys smoke (a lot, actually). Others like to pretend they're still in the military and do push-ups. Others mindlessly surf the Internet.
A lot of guys don't have an efficient coping mechanism that allows them to keep their minds engaged while not going insane. Some of the weaker-minded guys enjoy making fun and cracking jokes at each other's expense. It's all in good fun.
