So I'm at this farmer's market buying meself some homemade jams (peach raspberry & red currant.) They are $7.50 & $5 respectively. The friendly cashier clerk fidgets for a while before announcing the total - $12.50.
By that time I've set my sights on their fancy reusable bag, which is $2.50.
I'll take one.
The cashier clerk no longer looks friendly - in fact she's staring me down ostensibly. Her face says
are you really doing this to me?
She pulls out a calculator and starts typing away. I figure there's tax on the bag and she's never ever sold one before so she hasn't memorized the amount of the tax on a $2.50 sale. Fair enough.
So she types. And types again.
She frowns. Something is wrong.
She turns on the calculator.
She goes back to the cash register to inspect the screen. It reads $12.50. Ah yes, her face says. She remembers.
Back to the calculator. She types:
1 2 . 5 0 + 2 . 5 0 =
That'll be 15 dollorz.
