Still remember this, as a kid, reaching into the cupboard, pulling out a box of raisins, grabbing a handful for a snack, popping them in my mouth, realizing something weird was going on, reached in my mouth and pulled out a maggot. The rest of the mouthful went shooting into the sink about .5 seconds later.
This isn't gross, but we were at a ... Chili's, I think? And I'd ordered a boneless chicken platter, and I kept hitting, yup, little bitty bones. I kept extracting them from my mouth and assembled a little pile on a napkin. Just as a courtesy to the establishment, told the waitress about it, that they might want to check with their food supplier.
She was horrified at the pile. "Oh, I'm so sorry!"
"No problem. You just might want to check with your food supplier."
A minute later, the manager is at the table, apologizing like crazy.
"No problem. You just might want to check with your food supplier."
"May I pay for your meal, sir?"
"No, the meal was tasty. I just ran into these bones. I thought you might want to check with your food supplier."
He motioned to the napkin, not touching it. "May I take these, sir?"
"Chicken bones? Sure. Knock yourself out."
He folded the napkin and picked it up like it contained a donated organ.
"Are you sure I can't buy your meal, sir?"
"No, I pay my way. Good luck with your food supplier."
"Thank you, sir. I'm sorry, sir."
Evidently, they are sensitive to these issues.
