if you want a possible reason behind why this guy things there is a condom in his soup here it is.
In a responsible restaurant if any of the kitchen staff cut themselves they stop what they are doing and clean and bandage the wound. BUT after that they put on what is called a FINGER condom which for all intents and purposes is IDENTICAL to a for sex condom. but there is no lube and its A LOT smaller.
But the problem is the streach and degrade when working and exposed to grease and heat after a while. From that point onward it is entierly possbile that it can fall off.
Presto you now have a condom in your french onion soup that is NOT actually a “for sexy times” item
