I think that raw onions and garlic in the sandwich will reveal the perpetrator in a somewhat liability-free fashion.
My suggestion is heavily salt the food. No legal liability, no physical harm, and lesson taught.
Not temporary.
Just wanted to say that this is fantastic.
I think this could kill someone who responds agreesively to spicy food.
This would make a person want to die, but as mention… wouldn’t do much harm. Once as kids my sister made some brownies and used salt instead of sugar. After taking a huge bit and chewing a few times, I was unable to add salt to my food for nearly 14 years… TRUE STORY… no lie!
In our case, it turned out to be the boss. How much does the CEO of an Ad Agency make? Enough to buy his own PB&J, I’d bet.
He was caught with the laxative trick. There was no talk of lawsuits, just pain on the one hand, glee on the other.
Don’t put anything in the food, but if you do figure out who’s doing it, you could send them a nice little note after the fact, like " Stop stealing our food, eat this!" Along with this present, of course. http://www.shitsenders.com/
