When I feel someone is thinking this way ("true reason is laziness"), I instinctively react in an unpleasant way. I've been using a phrase "you treat me with less respect you'd treat a stranger" to remind them that empathy goes both ways, and I'm not their servant but independent human being.

I.e. if in the way you ask you show you're expecting them to comply, you're doing it wrong. Show respect to people's need for autonomy, and they'll be more willing to help you out.
