Many venues want to have an area that people can sit in or book but not let this affect your yield management. This walk through will show you how to create an area and let this happen. 

1) Located in Settings > Table Management -> Areas

2) Create a new area e.g. a Bar section

3) To exclude this area from your yield management. De-select Include in max covers/booking calculations  then click Save.

4) This will mean that any bookings in this bar area will no longer have an effect on your yield management.
