When I started my career as a chef we had very large mixing machines, like a giant mixmaster.
These never came with guards in those days but they did have a collar for sloppy mixes so they wouldnt flop out the bowl.
I once saw an apprentice pastry chef use a large flexible pallet knife to skim the mixture as the machine was turning.
Even after being told not to he continued.
The mixer blade caught the pallet knife grabbing it then flinging across the kitchen at near on light speed. It hit the wall and smashed a hole in the ceramic tiles.
Now karma enters the scene.
A couple of months later the same guy was using his hand to pat the large blobs of dough back into the bowl when it caught his thumb.
It actually wound him into the machine breaking his arm in a large number of places. The best part was having to unwind him.
Different hotel, very large 5 star in the middle of london.
The best one ever I heard was about a commis chef we called "Dumbo" not because of his actions but because of his ears.
This hotel had a basement kitchen with 120 chefs working. The Great room held 2000 customers and the smaller ballroom held 240 customers.
Dumbo had the duty of ignighting the gas hot cupboards before service so they were hot when we started serving.
These where two layers high and 30 feet long with multiple burners, each burner had an interlocked pilot and main tap like so
the object being to turn the pilot tap, light it then the main tap can turn through the cutout. (no safety cutout in those days, early 70's)
Dumbo went down the line turning all the taps on then was going to ignite at one end and the flame would travel all the way down the line igniting them all.
Picture the scene, all the gas taps on full, Dumbo patting all his pockets for a lighter, ooops, nothing, back to the lift, down to the main kitchen, lights a wax taper , back into the lift, up to the service kitchen, doors open and
totally destroyed the kitchen, two stainless counters blown through the wall into the street, blew the wall down into the restaurant and the only thing that saved him we think is the blast blew the lift doors shut in his face preventing the flash from burning him. Needless to say he was sacked.
This same hotel was having renovations done and a new customer lift being installed.
The builders were using jack hammers to make the holes in the floor for the lift shaft.
Started at the bottom and worked upwards. The bozo working on the fourth floor did--- yep you've guessed, worked all around himself like willie coyote and plummeted to the basement breaking most of his body. He survived.
I wasnt on duty that day but no one could stop laughing about it.
I refuse to tell about the ones I have done.
