Trying to seat a party at a gray table will produce an error message
“Warning. No server is assigned to this table."
The user can either "Cancel" or "Seat Anyway".
Pressing “Seat Anyway” will seat the guest at the table without a server assigned.
The user will need to manually assign a server from the Active or Inactive list to this table to capture the data on this guest’s visit and the server waiting on this guest.
