What would YOU have done with the briefcase?

I was just thinking about a strange incident which occurred while I was reading The Straight Dope on my lunch break, years ago.
I worked for a small, tourist trap shop in San Juan Capristrano, and I would often eat my lunch outside, in the courtyard between the shop and the train station. It was a pleasant place to read. I was happily fighting my own personal ignorance, when a perfectly coiffed businessman sat down next to me and started to hit on me. He had “asshole” written all over him, so I didn’t even look up from my book. If he’d been a nice person, I might have gotten into a brief coversation with him, but he acted like he was bestowing a great honor on me. I finally said, “I’m married”, then went back to my reading.
A couple minutes passed, then he said, “You’re pretty stupid, but do you think you could manage to watch my briefcase for me while I get a cup of coffee. I mean, you don’t need to strain your brain or anything. Just sit there and soak up some rays till I get back.” Then the idiot actually LEFT his case, and a stack of sales manuals, in my care. I never said a word. I finished my coke, grabbed my book and left his crap sitting there unattended.
When I related this bizarre incident to my co-workers, they told me I should have DONE something to his stuff, and one of them actually marched out back in a huff, to toss it all into the fountain on my behalf. The jerk was already gone.

I’m usually a pretty non-combative type, but every once in a while I daydream about what I MIGHT
have done. Tell me, what would YOU have done with his briefcase. Don’t hold back:D!

I think he was setting you up to open it, and it either would have exploded, or springy snakes would have leaped out at you.

I agree with your actions. Idiocy and rudeness are best ignored.

Is there any possibility that it might have been a sociology or psychology study or experiment? I’m thinking of that episode of ER with the guy who tried to get people to beat him up.

The guy sounds like a nut. Who would tell someone they’re stupid, and then ask for a favor? I think Eve is right, that suitcase (and it’s owner) might’ve been dangerous. You did the right thing by getting the heck out of there.
