I'm not sure which part of what I wrote is wrong according to you.

The value of any product or service is the price people are willing to pay for it. If he's getting custom for £35 fish and chips at Harrods, so be it. There's no compulsion for anyone to have fish and chips there. There are plenty of other places. Harrods is clearly not aimed at the masses. You're also paying for the ambience, using the fancy cutlery etc. And someone has to pay for the high rent at Harrods in Central London.
I still remember several years ago when I was desperate to buy Alphonso mangoes towards the end of season, not having tasted one all season. Ended up buying 2 mangoes for £15 at Harrods as that's the only place I found them, as opposed to buying a box of 6 for less than £5 elsewhere when available. I was prepared to pay for it as it's my favourite fruit.
