Revenge spiking
At a club I used to go to, someone started pinching unfinished drinks while punters were on the dance floor. One of my mates was a lab tech at a school, and obtained a quantity of a cyanide antidote known as "liquid Pickfords" - because it shifts anything. Basically it's a fast-acting double-ended emetic.

So a couple of pints were spiked and left temptingly on an empty table. Sure enough, the thieving scrote downed them. He barely had time to register that something was wrong before the potion did its work and reduced him to a shuddering, puking, shitting mess.

Not pretty, not kind, but drinks remained untouched from that day on...

Ha. I was never a fan of 'mine-sweeping'.

Back in the early 90's I allegedly prepared a small dose of phenolphthalein in a cheese and branston sarnie to punish the twat who used to sneak into the works canteen and rob the staff fridges of other peoples food, namely mine. Its an efficient laxative requiring only a tiny amount but one drop from a pipette was utterly fearsome and the miscreant was off work for a couple of days citing food poisoning to explain his sudden stomach cramps and repeated involuntary soiling of his undercrackers.
Apparently its now being withdrawn as an over the counter laxative due to carcinogenic concerns. Good! I hope he gets arse cancer.
