We have the option of not leaving gaps between reserves, in the opening / closing, or in both.

It is configured by activating the smart box option in the menu System → Web Tables → Booking Grids
This will only affect the reservations made in the Web / App.

If we indicate 60 minutes will not leave holes of 30 and will only work with the reservation box
This will only work if we have configured in the Web Page that the online reservation process is with the new reservation box.
