@GiantKitten massive house/multiple properties usually means lot of staff involved which usually mean that the family doesn’t really have to keep track of their things as other people are there to find them for you and bring them back to you.
But usually a house, no matter how big, is a house at the end of the day so you do get used to the size and you eventually learn where everything is or at least, should be!
Usually yes families will rather buy double or triple than carry everything over (except for the clothes) so sometimes even for rental holiday properties they will just buy what they need.
I mean I would say they probably lose stuff the normal amount but it’s the housekeepers/staff’s job to make sure everything is back where it’s supposed to be so that nothing is ever really lost.
Housekeepers usually work full shifts every day (or at least 5/6 days a week) so they are always there to check behind the family that nothing has been left behind and that if anything has been left behind after they have left a room that it’s either brought back to them or put back where it belongs.
@jay55 honestly I can’t speak for every rich person or celebrity but as far as I can tell they mostly order from the same places we do. The only thing is that they will eat a lot more fresh products and will splurge a lot more on meat, fish, cheese and wine!
If they have a chef they usually trust him/her to find the freshest produces and to make up the best/healthiest meals and I don’t think there is really a budget when it comes to food.
I know of one family who spent over 4000€ in one go at Carrefour (so barely a high-end supermarket) which was stock for a week or so. I personally have no idea how one can have 4000€ worth of groceries but mind you most host families feed their full-time staff, so the food budget is A LOT!
As for the most bonkers decoration. I mean I see a lot of lovely things as well as a lot of stuff I would never buy in a million year. Two things I remember, one who had machine guns, AK 47 and pistols in the shape of lamps in the kids room (they actually looked quite nice but found it an odd choice of decor for children’s room) and another was a cello that had been painted in very flashy but not harmonious colors at all with a bunch of what I wish was diamonds but was very clearly “cheap” gemstones and rhinestones all over it. And I just found it a total eyesore personally.
