To me, this seems clear, but let's see if others can confirm it. For a while now, I'm dealing with a type of customer who agrees to something, then goes back on their word. Like, if a new person calls me, and I'm filled up with customers, I tell them I can do this one-time thing, but I don't have time to take on a steady customer. They agree, but then once they "get their foot in the door," they'll save my number and keep calling me for other things. I tell them because I'm overbooked {and just one person} I'll take them, but don't tell everybody you know about me. They agree to that, then proceed to "advertise" me to one and all. If I'm tight for time, I say I can take them home from work, but I don't have time for them to make stops...
