Compared to home-cooked equivalents, fast food is more pricey, but that's what one pays for convenience. But what's really eyewatering are the prices for food at major sports / events venues.
Have done my share of cat shows and motor racing meetings, and generally, I will take a pack up. A sandwich and a tea is nearly £10 at the NEC...![]()
We looked into running a food stall at events over 30 years ago, £300+++ per day to be allowed in. I know of guys in my trade paying over £125 a day to stand in supermarket car parks offering windscreen repair, some come home very empty pocket.
