Why do people go to pub restaurants, where one of the overworked staff will put a frozen meal in a microwave until it goes "ding", then slop it onto a plate for you? Probably not the same reasons, and you'd expect a lot cheaper, though not as cheap as the same microwave meal from the supermarket.
Do people go to what they think is a real restaurant, because its marketing has diddled them, but find out it's actually a pub restaurant when they get there, replete with low-effort slop? If they do, I hope they leave a terrible review and don't come back.
Obviously I can judge a place based on the quality of service and food, but that's not the reason I've gone there in the first place.
