Buddy of mine had a plethora of different nationalities at his old job. They were all cool with each other, but he had everyone write in their native languages “DO NOT TOUCH” on his lunch box. Not that there was ever an issue, but still funny. There was even tagolic written on there.
So did anybody mess with it? What I did to cure that crap was to bake some cookies. They were my grandmas receipt (very good), and brought them in to work under the guise that I made to many. The next time I put certain chemicals (some safe, some not so safe) in the mix. got to work and mentioned that I made cookies again, but I only made enough for me so I cant share. sure as can be by first break they were gone. by 9:15 there were two guy’s puking there guts out, and crapping them selves. never had that problem again.
