It's fun when you see these things happen and you're not the one being absent-minded for a change. (And nobody gets hurt)
I had to get gas this morning. I work early, so I was at the gas station at about 5:15. It's dark out and nobody's really awake.
The guy in front of me started his gas pumping and went and sat in his car. The pump clicked, he got out, punched some buttons, washed his windshield, got back in, and started driving off....but he never took the nozzle out of his car!! I started yelling but he didn't hear me in time. The nozzle and about 4 feet of hose came off of the pump (those things have a quick release) and he stopped and had to do the walk of shame to bring the hose and nozzle back to the guy inside. I could tell he was completely embarrassed! I was trying so hard not to laugh....not at HIM exactly, just at the whole scene. That's the third time I've seen that happen!! Some day it'll be my turn, I'm sure...
