I work at a retail store in the historic shopping district of a small-ish town. It's popular with all sorts of people: tourists, people with more money than sense, rude people, smart people, nice people, idiots, etc. This can lead to some interesting stories. Some stick out more than others. This is one of my favorite exchanges of the day:
"So, if I don't see a jar of something...do you not have it?"
"Uh, no. I can jar it up for you." (That's me, by the way.)
"So you'll jar it up? In a jar, right?"
"Yeah, I'll jar it up for you."
"But that will be in a jar, right? Because I want it in a jar. So, you'll jar it up?"
At this point I just smile broadly and go jar it up.
Seriously. It's not rocket science...
