Asking for the bill
When the guests ask for the bill, go into the table, tap Order and then the Ask for the bill button at the bottom.
The PDA asks PizzaGest for the bill; PizzaGest applies any offers that apply and works out the total. Meanwhile you will see this message:

In a few seconds the bill summary appears, just as it will print on the receipt: the products, the offers applied with the products each one includes, and the total.
Below the summary there are two buttons:
Print the bill: the bill is printed on the restaurant's printer. When it is done, the PDA shows the message Bill printed and you can take it to the customer.
Exit without printing: goes back to the Orders screen without printing anything.
If the customer prefers other offers than the ones applied, exit without printing and apply them from the computer.
If there were products not yet sent, they are sent to the kitchen when you ask for the bill. And if any products were marked for removal, the PDA asks you to confirm first.
If PizzaGest does not answer
If 30 seconds go by and PizzaGest has not calculated the bill, the PDA tells you:

Send the order without the bill: the order is sent and the bill is printed from the computer.
Try again: asks for the bill again.
The most common cause is that PizzaGest is not running on the restaurant's computer.
If the message The bill could not be calculated appears, the table may be open on a computer. Close it there and tap Try again.
