Satisfied?

The checkout attendant tightly scrunched the note she'd been handed then released it onto the counter.

There was a pause while she (and I) inspected the unsprung currency lying before us.

She lifted her eyes briefly to meet mine and then, satisfied?, completed the transaction.

Are you checking for counterfeits?

No, I don't know, the boss just tell me to.

But why? What are you checking for?

I don't know. If it's a hundred the boss ask.

Sorry, but what I mean is what is it you're aiming to find out by doing that?

I don't know.

But then there's no point in doing it, is there?, if you don't know what you're doing it for.

I know.
