Likewise, no one is forcing people to use delivery apps. The apps provide a benefit of convenience without a huge cost overhead. If people don't want to use the apps, they shouldn't use the apps. If they can get higher value by going to restaurants directly, rational customers will do that.
Delivery apps are simply helping to sweep the market clean of inefficient mom'n'pop food shacks and helping us get to healthier business reality where restaurants are better aligned with diners. Have you seen Gordon Ramsay's Kitchen Nightmares? Most restaurants are run by insane people who have no idea what they're doing!
If diners really expect undeliverable value and restaurants must be held together with duct tape and baling wire, it is an unhealthy market and will naturally destroy itself.
