In vampire movies, the one way you can avoid the vampires is by not inviting them in your house. So, what are these restaurant owners doing? Inviting the vampire (Chuck Schumer/Big Government) into their businesses. If Grubhub, DoorDash, UberEats, or any other delivery service doesn't work well with your company, then get your own delivery drivers or stop offering delivery.
Asking Chuck Schumer (or any other elected official) to fight your battles only gives him more power to tax you, regulate you, and eventually crush you. Don't be dumb. https://nypost.com/2019/07/22/schumer-demands-grubhub-ceo-refund-all-overcharges/
