I have received a few uninstall reviews on my FB page, and one 2 in general that were total lies.
I've learned that a restaurant can not please all the customers they serve all the time. All we can do is try.
I resisted allowing delivery service for a long time just because of the nature of the food delivery.
My restaurant offers a top quality stake, many comment that it is the best in town.
I started using Door Dash, and seen negative reviews on our stakes. Some one orders a med-rare stake and the stake is placed in a take out container that is designed to keep food hot, the stake continues to cook while in route to the customer. When the customer receives their meal the stake is now well done, or close to it. The customer is then pissed off and goes onto Doir Dash and leaves a bad review. This review hurts the business, and the writer of the review orders else were next time.
I found that a person can come into the restaurant and have several meals with no negative issues and then try the home delivery and end up writing a negative review. The best path forward is to be careful what you order, and don't expect it to be quite as good as you expect. If you want top quality then go out and eat, and then judge accordingly.
These companies all use the same drivers. It is a pool of drivers that deliver for all the services.
