This kind of took me by surprise as I hadn't really thought about it. Actually, to be honest, I was more concerned about getting positive reviews from them, which IMHO leads to more business. I guess I would say I wasn't too worried if they didn't come back for more.
Just makes you wonder though about those who look for freebies, are they really trying you out to see if they will order more from you, or are they simply looking for a free handout and then moving on to the next service provider?
What have your experiences shown you? What are your thoughts?
