I totally agree with comments about defining a slot for a customer order/ changing the process for collection or delivery in the #WixRestaurants app. In this current time of Covid-19 has anything further progressed with this or other suggestions for Wix Restaurants? Could possibly an alternative be looked at say at opening time have pre determined booking slots through from opening to closing for customers to select when they would like to pickup food ordered via the menu. According to how you plan out your pickup slots for food service, so if you have a rushed period you can alter the timing slots on the fly via the app. #featurerequest
