Waste
Start by ringing up the item(s) that you are wasting. For example, in this case I have made the Caesar Salad incorrectly by tossing it with the dressing when the customer wanted dressing on the side. Although I have already rung up a ticket for the customer's order, I will ring in another Caesar Salad to account for the one that is being wasted.
Before finishing the ticket, go to Options and select Waste.
You'll be asked to confirm - Are you sure you want to waste these items?
The system will automatically set the price to zero, record a closed, dine in ticket, and add a message to the ticket that says "Waste Item"
The system will deduct inventory for these items, and will report the waste on the Operations > Waste report.
Tip: Waste is a secure function. You can set this in the Security Settings under POS Functions.
