My right thumb is a about 3/8ths of an inch shorter than my left, thanks to a Hobart Slicer at the restaurant I worked at before the Reuben E. Lee.
I was head chef (at age 18) of the Hamburger Hamlet in Costa Mesa, CA, where we had a nine page menu in fine print, and a chefs line with seven chef stations, and on busy nights, seven chefs. (Broiler, fryer, grill, sauté/breakfast, sandwich, salad and dessert.)
I didn’t even realize I had a problem until the white onions I was slicing up turned red.
I lived at Hamburger Hamlet on the Sunset Strip as a kid and remember the menus. I thought I was so sophisticated!
