Well, we're mucky buggers compared to some then.
We have 4 crockery plates and 4 melamine, the 4 crockery ones are there so they can go in the oven or over a pan if it's a hot meal, but we do have a lot of cold meals in summer, 8 bowls of 3 different types, 4 mugs, 6 tumblers, and enough cutlery to start a café, two saucepans, two frying pans, (we don't eat much fried food) they are good for warming flatbreads with a little olive oil or just warming food and an assortment of tray thingies for the oven and a grill pan.
The pans get a splash of water and a dash of WUL, plates for toast or sandwiches get a kitchen roll piece and re-used, plates get wiped into the bin immediately after the meal, and may get re-used or into the WU bowl with some water and WUL so they get partly splash washed on the journey, cutlery gets rinsed and if ok re-used, 4 days is easy but can be longer in winter, but we do eat out so a week is not unheard of, what dictates the frequency is the saucepans, even though we wipe they are more stubborn so need washing usually, the frying pans wipe clean easily.
One of the reasons is to save on LPG, and of course, water, as WU is very wasteful of both, and not cheap to replace as you have to go looking for water which uses fuel which can be better spent, also the drain hole is always in the wrong place to actually do the job properly.
No doubt we'll get criticised but hey ho.
