Clerk: $12.30.
Al: Oh, sorry, I'm short $2.30.
I only have $10 on me.
or
Can I get a discount?
Clerk: Ok, well, $8.70 then.
Ok, well then how about $8.70.
Al:Thanks, here you are.
OK. You've got a deal.
That's good.
(I give him $10.)
Clerk: Here's your change, $1.30, thanks.
$1.30.
p.s. $10.00 - $8.70 = $1.30. I said "$1.20" in the video. My bad.
