What A Rip Off!

(I am working as a cashier. A customer brings up a toy in a plastic container, and when I look for the price tag to scan I notice the tag is gone, but I can clearly see where it was ripped off.)

Me: “It looks like the tag got ripped off of this item; we’ll have to do a price check.”

Customer: “Oh, this is a gift. I ripped the tag off myself. I forgot you’re not supposed to do that before checking out.”

Me: “…”

(It’s also worth noting that she said the item was $9.99. We found a similar item with a tag that I could scan, but it was $7.99. She got a discount for being dumb.)
