Yeah my overall spending at McDonald's declined significantly after the 2022 bout with inflation, and it's not just that prices went up (it was inflation, they mostly all went up), but that they leaned into trying to appeal to people who would already have been spending lots of money.
It would have been one thing just to make the food taste better, but they went the opposite and made it take forever to prepare and serve. But for me the whole point to McDonald's was to get in, eat something consistently decent, get out quickly. So they actually made things worse, because I already had plenty of other spots to get "nice" food if that's what I was in the mood for.
I'm not going to say bring back the heat lamps per se but there was a lot of value to people like me in having a restaurant that delivered on the original promise of "fast" food...
