I pack lunches for both of us and deli meat is outrageous. Lately I'll make an extra meatloaf for sandwiches or a batch of egg salad, eggs are still cheap.
Now, question.
I'm not putting it down if decent and civilized people do it, because decent and civilized people are careful how they do it. I'm putting it down only if primitives do it.
I dunno why the following is; maybe it's because of the sensitive Nebraska Sandhills nostrils, used to nothing but the cleanest, freshest of air flowing into them.
It's easy to get nauseous sitting close to a person in a break-room chowing down on a packed lunch.
Even as a kid in grade school, I noticed the phenomenon.
The ripe combination of odors is never pleasant, no matter what it is.
Best to just eat lunch prepared on site, in the break-room or a restaurant.
When I was in college, I had a boss who used to bring a wife-made packed lunch to work, in one of those old-fashioned metal lunch-boxes shaped sort of like a barn. The box itself was about as old as I was, and had by then "absorbed" the odor of at least two decades of home-packed meals in its metal and rust.
When he came to work every morning, he put his lunch-box on his desk, and then headed to the men's room, because his wife, who weighed 400 pounds, didn't like him stinking up the bathroom at home (he stunk up the one at work pretty good; no one could use it again until about noon).
While he was in there doing his ablutions, I would open up his lunch-box to inspect the contents. It wasn't ever a pretty sight. He knew I did it--I was actually caught about a dozen times in two years--and sometimes there'd be a wrapped cookie or something, my name on the wrapper. But three times, he hid an unsnapped mouse-trap in it.
Ah, good times, good times, the good times of youth.
But most of all I remember the stench; I always had to hold my breath when opening the box.
Primitives who pack lunch think they're being frugal, but they're being rude besides. The time and trouble of making them, and the odoriferous discomfort it causes other people, cancels out the money they save.
Better, cleaner, cheaper (in the end), quicker, just to buy food prepared on site.
