Anti smoking robot

Q: What would you do if there was an anti-smoking robot holding you at gunpoint telling you not to smoke anymore??

A: First of all, I'd question his motives.

Q: He'd say "you're damaging your lungs and it would help the greater good if you quit"

A: ok so there's the problem. What good are my lungs to a robot??? Clearly he wants them for an evil robot reason.

Q: Lets pretend he's a reasonable guy

A: No such thing as a reasonable robot. I would have to put my foot down in this situation. 

Q: what would you do??

A: Ever see a robot and human fist fight???
