Have you ever seen a cook or waiter/waitress tamper with a meal? (NSFW)

I have lots of stories. I don’t want to get sued so I will leave it at that for now. Some are that bad.

I will mention the one from Subway in Jasper National Park, 20 years ago, before It moved. Drunk people who piss off the sandwich artist would get EXTRA hot sauce to the sub. The intoxicated man would vomit it up later after trying to consume.
