I saw this happen with a local chain restaurant recently. They started cutting on ingredient quality and it was noticeable. Noticeably smaller tortillas; you could no longer opt out of onions because toppings were all combined; chips went down hill. They started losing profits, had to close a few locations, and the negative reviews started rolling in.
The end result was positive though. They saw the response and reversed the changes. They’ve gone back to their previous quality and turned things around at least a small amount. They made good with the customers—the people that are the reason they exist in the first place. I wish more places would have a similar response instead of doubling down on the enshitification.
