Funny thing is, besides the sausage, all of that shit could have been bought at stop and shop. He's not acquiring hard to get italian or premium exotic ingredients lol. Getting upcharged on coffeemate because you are above going to a normal store then bitching about the price is such a perfect boomer Facebook post
Truly wealthy and money-savvy people cut their corners well. They'll do as much banal essentials shopping as possible at Lidl, Iceland, Argos, CostCo etc, then either invest/donate the rest, or splurge on a few stealth-wealth status items or leisure activities, like health retreats and holidays to rare locales via private plane, no-label label clothes, pricey exclusive restaurants you or I wouldn't know, fine art, their pony or their boat.
And with these types, it's not as if they couldn't easily afford Uncle G's or M&S or Fortnum's or Whole Foods. They're just cheap canny cunts and they like to have cash to splash on the right things.
