Give Them A Taste Of Their Own Dry Cleaning Fluid

Tough stain on a piece of clothing. I take it to a dry cleaner. After a couple of days, I go pick the item up, and the stain is still there, but they've attached the cute little tag seen above. They want me to know that they didn't forget what I asked them to do... just that they couldn't do it.

They do, however, send an invoice.

No problem. I respond in kind.
