I've been searching for this one fruitlessly and I'm sure I didn't make it up or dream it up...
Pretty sure it's in Polish. A woman with big breasts is ordering some meal and is asked if she wants mustard or mayonnaise. She picks the white bottle, which is a squirt bottle. The server sprays the substance into the air, which mostly lands on her breasts and partially her face. She's surprised, then angry and stomps out.
