Efforts to entertain me gladly accepted

My friend Harry works for a national auto parts chain: Last week, he related this story to me (BTW, gas is $3.59 a gallon).

Earlier this eve, a chap came into my store, asking for a locking gas cap.

I got it for him, and I mentioned that we seem to be selling quite a few more of them lately.

He then asked if people are stealing the gas caps.

I then told him that no, they're after what's under the gas caps.

Yep... this really did happen...

He asked what's under the gas caps.

I said "Gas."

Here's your sign.

Today - he sent me this addendum:

Someone else came in for a locking cap. Got him the right cap, sold it to him. A few minutes later, he came back in, he couldn't figure out how to use it. I went out, verified how it works, showed him how to use it. A few minutes later, he comes back in... he still couldn't figure it out. Manager goes out, same deal, even put the guys hands on it to show him. He still is having problems.

A few minutes later he came back in for a refund.

Got his refund, and his sign.

A little while later, manager has a tote bin of parts in from the hub. He breaks the seal to open it, I wandered over to see what's inside out of curiosity. Bet you'll never guess what the first thing we see is...

Yep. A locking gas cap.

A little while later, manager is looking up a part for a customer. No problem there, until I walk behind him and say "gas cap". He starts snickering, customer is wondering what's going on, and I get a dirty look (slightly) for cracking him up.

A little while later, customer comes in, asking me if I could test a coil. I had to tell him I couldn't as I don't have an ohmmeter. I told him how to test it, and tell him a little about how it works. He mentions something about it being similar to a transformer, to which I agree. We're done, he wants to pay for an air filter, so we go over to my register. It was then that I noticed his t-shirt and ball cap... both sporting the initials "IBEW"... International Brotherhood of Electrical Workers. It was then I called over the manager, told him what happened, pointed out his t-shirt, and nominated myself for the Locking Gas Cap Award. More snickering.

Where's MY sign?
