There's just two of us, why would we put out service for three?
Everything I use to prep gets cleaned and put away while the dish is
cooking... by the time I serve there is nothing to clean other than
plates and utensils we're using and that takes me ten minutes right
after eating and brushing my teeth. Left overs are still cooling in
their pot so go into the fridge later and the next day I portion them
for the fridge and for the freezer, and scrub the pot. People who
actually know how to cook clean as they go, unless they have a maid.
Restaurant cooks don't need to clean as they go because they have a
maid who scrubs pots, pans, bowls, etc., usually refered to as "Deep
Sink Willy"... a real commercial kitchen contains no soaps or glass.
Restaurant dishes and eating utensils go into a large dishwasher in
its own room, the scullery. Barware is washed by hand by the
barkeeper, when a table is cleared the barware is returned to the bar.
Some restaurants have a separate more gentle washer for glassware.
Restaurant cooks do clean their personal items like knives.
At home I wouldn't put my cookware/bakeware/cutlery or woodenware in
the dishwasher anyway, nor good glassware. Even our good company
dishes and eating utensils are washed by hand. Most of my
cookware/bakeware won't fit in the dishwasher.
We each use the same coffee mugs every morning, afterwards they are
hand washed and put back on their cuphook all ready for the next day.
I only have coffee in the morning. My wife drinks tea all day and
uses the same cup all day, just keeps refilling it... typically ends
up on her night table so is washed in the morning. Everything in our
home lives in a particular place, especially in the kitchen, that's
one reason why I do all the cooking, everything gets put back where it
lives. When I arrange the pantry items everything is lined up like
soldiers with all labels facing front. Everything in our fridge and
freezer is arranged in a purposeful way, I never need to search, even
in the dark all I need to do is reach in. We're very organized, a
dishwasher would wreak havoc on our routine, would just cause us
grief. We both like to have everything returned to where it lives all
ready to be used again, immediately, same as normal people do with
their toothbrush.
