In 1990 I agreed to pay £3500 to have a nice oak kitchen installed by MFI. I paid a 10% deposit before work started.
When the fitters turned up to fit the kitchen they discovered that the salesman / surveyor had measured it wrong and the units wouldn't fit, so they had to fit a smaller cupboard at the end of the walls.
I nipped out of work to meet th salesman and ripped his fickin ears of. "Never mind Made For Idiots, its sold by fickin idiots, was one phrase I can remember yelling at him.
Anyway, once fitted it was a lovely kitchen, and what made it nicer was that I never did receive a bill from them for the balance of £3150.
As for Ikea. In the late 90,s swmbo won a £1000 Ikea voucher, and wanted taking there to spend it. Daughter was also moving into her first flat so she wanted to come too. I borrowed a Transit pickup from work and off we went on a Saturday morning.
We were there when they opened, and didn't leave until after closing time. They had these big trolley things you put your flatpacks in and I was relaying four of them around the shop until we got to the checkout, which took hours by the way.
I was almost too knackered to drive home.
I still break out in a cold sweat thinking about that day. I swore I would never go back, and I never have.
