My dear @DarthCoin, Thank you for your detailed comment :)

The drink shown is called Spezi or Cola-Mix, which is a mixture of cola and orange soda. It is often sold in beer bottles.

Our merchants place great importance on this; however, it is up to each individual to decide how and whether they declare their earnings for tax purposes. At @OPAGO_PAY, we aim to provide all the tools necessary to offer a reputable payment service.
