There are loose nuts everywhere, and if they are having a bad day, you might be the one they take it out on. I had a guy get furious at me for not pulling up in the McDonalds drive thru fast enough. He followed me through a parking lot so he could unload his anger......i guess he didn't enjoy his burger because I hadn't gone by his time table. I figured it out, and I couldn't have been more than 10 or 15 seconds later than usual. I forgot there were two lanes and not one like the Wendy's, so I didn't pull up right away. He had to wait for his food when he got there anyway.......what a nut.
