Multiple/Duplicate Bookings in same day

If the previous booking has not paid yet, there will be 2hrs buffer time If the booking is paid already, no buffer time.

2hrs Buffer time If Pat created a booking that has dining time at 12:30, the fastest time Pat can book again is 14:30. *The buffer is comparing between current and new dining time. Not time that pat make a booking in real world

*Remark* The Booking can not make on the same Resto in the same date if the previous booking is not arrived
