When I lived in the states I didn’t know anyone wealthy enough to have a house, so no laundry shoot. Top loaders can fit far more, I only needed to do washing once a fortnight and it would all easily fit in the machine.
With sandwiches, yes sliced, however american sliced bread is much smaller than British sliced bread, so when slices the two halves are quite small. The photo I’ve attached shows typical sliced bread in America and a slice of what I think is wharbutons toast bread, the wharbutons is much bigger.
Supermarkets with a deli will make sandwiches to order much like the pizza bars in british supermarkets, usually rolls etc rather than pre-sliced bread and mayo rather than butter or margarine.
Due to the wattage kettles take longer to boil, and they aren’t needed for coffee or cooking. I do drink tea, but I don’t drink tea from tea bags, so despite growing up in britain I’ve never been a kettle user.
What I found handy in the flats I lived in was communal trollies in the underground carpark to get lots of things back to your flat in one go, very large bike parks, secure stores etc for communal use.
