Leaving the keys in the 4 bay beer truck for 10 minutes unguarded.
Sitting around for two hours waiting for the police to fill out paperwork and a coworker to bring a new set of keys. At least I'm getting paid for the time.
Agreeing to go out drinking with friends to celebrate my 21st birthday "right"
Finding out at 2am when I'm three sheets to the wind and three of my buddies are passed out in the back seat, that our designated driver has 'poor night vision' and was also completely color blind. The trip home was a long string of 'Red' 'Green' 'Red' 'Green, no Yellow... Red.'
