I served a couple yesterday. The girl was looking for small or medium sizes for a set of rings which was not available on the rank. Finally, she decided on the small ones.

Daisy: Eh, the customer wants to purchase this set of rings.
Colleague: Orh, okay.
Daisy: Yah, four rings for $19 hor!
Colleague: Eh, you must inform the customer that actually we're selling one ring for $19.
Daisy: Are you serious? Nah, you're kidding.
Colleague: Serious! You must inform them!
Daisy: Then what is this? (held up the medium sized set of rings) Aren't they four for $19?
Colleague: No, the other three are for display. The truth is one for $19.
Daisy: Yaya, you liar. Why not you scare them by scanning the barcode four times?
Colleague: Hahahahahaha...
