A colleague was so cheap he’d buy cases of peanut butter and saltines at discount prices and live on that...and bank the per diem food allowance. He’s probably a multimillionaire today. He must have been ex-military. A can of tuna, some mayo, crackers and cheese is still a favorite of mine.
At my office, I bring in for lunch either tuna fish, peanut butter and jelly, fluffernutter, chicken salad, sardines or meat sandwiches. I bring in leftovers, too.
Coffee and chips? My BS meter is pinging!!
