This evening I watched someone attempt to use one to buy paracetamol. The particular self-service robot checkout that I saw presented the user with a message very much like “paracetamol sale: you may only buy two packs” above a yes/no button pair. What is the casual paracetamol buyer to make of this? I watched with interest as my co-emptor pondered this. And then she did the only reasonable thing: she went and got a second pack. After all, it does say you may only buy two packs.
Quite what anyone is supposed to make of the yes/no buttons following a statement not a question I don't know.
The really sad thing is that, apart from the shame of confusing your customer, the behaviour I saw here—which I believe is the only reasonably response to the message from the robot—is the exact opposite of what is intended.

That's pretty bad. It would be far better if a prompt (not that one!) only triggered when a 3rd pack was scanned, and otherwise not bother the customer.
Another favourite of mine is when the system asks you if the price is correct, as if I would have some superior knowledge. I usually press "yes", but next time I might try "no" and see if I can enter my own price...
