Plastic utensils, moist towelettes, paper plates and bowls, paper or plastic cups, how did people eat quickly on their way somewhere, or go on a picnic, for all the years, centuries, before these conveniences were invented?
They took the real stuff with them, is how, and brought it back home and washed it as usual.
Convenience is great, and the older and more tired I get the more I understand why people go for it. On the other hand, I have more time than money, so it does me no real harm to use real utensils and dishes and eventually* wash them up.
When life calls for me to take a meal with me I use an insulated bag, possibly with a small blue ice in it. The beverage goes in a stainless steel water bottle. I wrap flatware in a cloth napkin and put the food in whatever reusable containers are suitable. A scrap of cloth, dampened, in another small container, works as a moist towelette. After all, moist towelettes are just a disposable substitute for the good old damp cloth people had always used.
My intention here is not to campaign for never using disposables. My hope is to let people who are trying to spend less and save more implement one more way to do that.
*I’m not among those noble people who wash dishes after every meal. That might be an argument for using paper dishes, but no. Because there are other people in my household to be considered, I daren’t fill up the sink with my dishes. I rinse them and put them in a dishpan off to the side on the counter. Because they aren’t sitting in water, they don’t develop a stink. When I’m ready to wash them I fill the dishpan with hot soapy water and leave it to soak until the water has cooled off enough to be comfortable for my hands.
