I tried, fiddled around with the terminal for a good five or ten minutes trying to find it. It's obviously just hidden because the "function" menu is numbered and there are large gaps in the numbering. Attempting to type in a "missing" function number (I presume one of them would be "void") asks for a "bank password".
In that case the manager was called and after making a scene (and showing them that pushing "cancel" on currency selection screen did not cancel the whole transaction with an example purchase of a plastic bag) they gave me back the difference (and the charge for the bag) as cash out of the till. I thought they learned when the terminals started presenting currency choice again. Obviously not.
I assume you reported them to visa or mastercard and then if they refused to void or cancel the transaction that you didn't want the item and walked away and then returned and asked to pay with Amex which doesn't allow dcc (or do they circumvent their rules too. And what happens if the clerk makes an "honest" mistake and enters 100.00 instead of 10.00. You mean there no provision to correct such an error. There must exist a password to void a transaction. Either the manager was not told of it by an even more senior manager or doesn't want to use it. I would never allow anybody to get away wth garbage like that against me.
