Do you go to icecream stands and the like which give away "free samples" and sit there eating all day?

Would you take advantage of something that is free? Be honest. Of course you would.

If I was asking someone to do a job for free, I'd like to think I wouldn't just keep heaping work on them. A workman is worth his wage afterall.
Yet, sadly, but people really do this. You do something nice for them and they expect it every time (and more and more). Then you're the one who feels bad when you have to stop it.
I usually say: I can't do that for free as I've already done XYZ and I can't do more without charging. That usually stops them or makes them pay (usually it just stops them).
IMHO charging a nominal fee is better than free.
