Window cleaner is paid by bank transfer (as are the cleaner, garden, and the man who does stuff). Milk, I have cupboard-load of UHT stuff lurking in the kitchen and we don't use much as only I drink hot drinks and I eat toast for breakfast and her ladyship buys breakfast on the way to work to maximise her sleep time.
Cleaning cars is indeed the talk of craziness, that's what rain is for*.
Of course, one of the benefits of only occasionally going to the mothership means I loaf around at home and I don't have to pay to take things out of the fridge.
*OK, it occasionally gets cleaned by the men in Sainsbury's car park. But that's on my wife's watch as I don't drive the car and she only goes to Sainsbury's get a particularly brand of sweetcorn which she's strangely addicted to (salad crisp apparently, and it does taste nicer). Seriously though, she looks mental pushing a trolley with 24 cans of sweetcorn, two boxes of cat food (for the charity bin), and occasionally a bottle of gin, so I disassociate myself.
