The pizza delivery guy kept asking me to sign but I told him I cannot sign this because I won't acknowledge the fraud. He claimed he was new and had no idea how to do a refund.
Which is entirely possible. Because the merchants there lease stuff and never do their own, it's possible that nobody really at the store would know what to do - they just lease the terminal and get told by eservice how to run it. So a delivery guy - much less of a chance he'd know anything either.
I remember getting delivery from Domino's and I was vigilant and an older gentleman with a mustache (

) got very perplexed when he saw the DCC prompt - he started mumbling "uhhhh USD or PLN what is this?" so I told him to hit PLN.

So he clearly had no idea what this is all about.
