That just reminded me of a story.

I have a reasonably wealthy cousin who, on occasion, will search out these timeshare (or whatever) offers that give you a small vacation just for listening. Then he shows up to the place and immediately tells the person that he has absolutely no interest in purchasing the timeshare (or whatever). If he wants, he'll be happy to sit there for several hours while the salesman makes his pitch, at which point he'll say no, or the salesman can let him go right then and put that time to much better use on someone who might actually buy something.

Much more often than not, the salesman tells him to leave.

Under most circumstances, I'd find this fairly unethical behavior, but I find it hard to blame someone being unethical to an organization wholly unethical to begin with. Plus, it's funny.
