> What if you know, clearly, that your interaction what not what the designer wanted? This is what I like to refer to as “stupid tax”. I’ve had cases where I put money into a soda machine and it gave me a drink plus more than I deposited into it. Or kicked out more than one item because one was stuck and my purchase obviously unstuck it. Does this make me a criminal? As an aside I used to work at a place with a soda machine that was basically like a slot machine with slightly higher payouts than one in Los Vegas. This was at a grocery warehouse and the drinks were at cost so “losing” your bet cost like a quarter. Probably designed that way, who knows?
