This happened to me, but it was the merchant that clicked it...

I inserted my card, and then was reading the text and choice that popped up on the screen, and while I was reading it trying to decide which I should click, the merchant grabbed the scanner and clicked the accept...

Of course I got a charge notification on my mobile app immediately and noticed that it was way higher than it should have been, so then I had to go back to them and get them to refund the transaction so we could do it again which took forever and a manager etc etc.

I've also learned that it is a good idea to physically put my hand around the payment thingy to make sure I am the one pressing the buttons.
