A guest ordered from the table QR while my waiter had the table open. Why did it show two orders?

It no longer does. A guest's QR order on a table the POS has open becomes the table's bill: the dishes the waiter already typed move onto the guest's order, so the guest's order page and WhatsApp stay right, and the table shows one bill. A table tapped by mistake is not a bill at all until its first round is sent, so it leaves nothing behind. If a table was left holding two orders from before, the tile says 2 orders and a tap joins them into one bill. The Tables, tabs and the kitchen screen tab in the docs covers QR orders on tables.
