This machine gives you a ticket for the parking garage. For starters, you have to ticket sleeves (which is which) and one green button. The drill is: you push the button, get a ticket and you are allowed to drive further. The problem is that after pushing the green button you keep your hand there while waiting for the ticket. Then after a while you notice that the ticket has already come out but you have been blocking the view with your hand!!! As a result you feel really stupid. You have been focussing on the wrong ticket sleeve.Btw. I haven't even started about the industrial design....
