Talk about your day going down the drain. Im sure it has happened to someone, somewhere. That could be a thread all on its own, "Where's the worst place you have dropped your keys"...
After the first time I locked my keys in the back, I learned a valuable lesson; to
always keep the key ring around my finger like we were taught to do as newbies.
I learned
another valuable lesson soon after; that the "keep the key ring on your finger" rule should
not apply when you are standing at the urinal taking a leak.
There are few things in life more hideous that having to pluck your keys out of a urinal. The fact that they are marinating in your
own pee vs. someone elses is of little comfort.
