Use case: As a bartender at a canteen, instead of creating a payment request for a customer for each order, I want to be able to add items to a bill so that the customer can pay the bill at the end of the evening. Typically, this occurs when someone is buying the drinks for his friends and has an agreement with me, the bartender, that all drinks can be added to his bill (e.g. birthday party) and can be paid at the end of the event.
Typically in other cashier solutions, a bartender has the option 'book to account X'
possible solution
possibility for an admin to define a set of wallets in the TPOS config
When checkout > pay, as a merchant i have the option in the TPOS instance to charge one of the predefined wallets, without explicit authorization from the wallet's owner
