What did he typically eat?
It's been so long ago I barely remember. I recall best that his wife used to fix him a couple of sandwiches that had the odor of warm mayonnaise emanating from them, but I could never figure out what the sliced meat was; it was always not-quite-all-the-way-baked white bread, which causes me to cross my eyes and go "Gaaaaaaaah...."
Then there'd be semi-liquid stuff in a couple of little Tupperware containers; my generic word for it is "glop." His wife like him was a German from Russia, so I assume it was along the nature of that cuisine.
Sliced liverwurst. Gaaaaaaah......
Sliced spiced ham (bologna?). Gaaaaaah.....
Limberger cheese. Gaaaaaah.....
Cold
sauerkraut. Gaaaaaah.....
Some sort of sausage shaped like a horse-collar.
Something for dessert; a piece of cake, a brownie, or some cookies.
An apple, a banana, or an orange.
Inside the lid was a thermos of coffee, which confused me, because the business was generous in providing gallons of coffee to all its employees, and he had no qualms about drinking that coffee, but still, he'd bring in the lunch-box with coffee in the thermos.
To put it mildly, it all stank. I'm sure his wife washed out the lunch-box (which was plastic, not metal) every single day, but I'll bet all these odors got permanentized to the inside. The aroma made one want to give up eating for the rest of one's life.
To this day, I have a shuddering abhorrence to being around people bringing lunch-boxes and sack-lunches to work. Those times I worked at a place where the lunch-room had a refrigerator in it, well, I just went somewhere else.
