Limit number of bookings per time slot#1003

Most Customers are booking for the same time specially for occasions like Valentine’s Day , getting the restaurant busy for a particular time and empty rest of the time. For Example all bookings coming for 6 pm, after the restaurant is empty and calling the customer ti switch the time or rejecting the booking is a hassle. just like limiting pick-up and delivery order. If we can limit reservation per time slot.
