> If (say) 30% of the restaurant's patrons choose to get the food via food delivery, why shouldn't those folks' ratings of the food be factored into the restaurant's rating?
If the restaurant has chosen to focus on dine in service because that generates the much of their revenue (alcohol sales, desserts, etc.), it would be a shame if their ratings were damaged by delivery customers. People check ratings/reviews before dining out, so having a bunch of bad reviews due to unwanted delivery could really affect dine in traffic as well. It's not fair to expect the restaurant to cater to these delivery customers when they not actually chosen to run a delivery service.
