FNB More Ordering Terminals

When 1 user is ordering on a terminal, 2 scenarios, 

1, he chooses a table and creates a new bill, system will indicate this table is occupied by this user; 

2, if the user recalls bill, and choose one bill to edit, system will also indicate the table in the bill is occupied. 

At the two scenarios, if another user uses another terminal to try to access the same table, the system will alert him that the table is locked by which user.

Once the User Hold the bill, void bill, or settle the bill, system will indicate that the table is released. at this situation, any user can select this table to order.
