E.P.
I'm a Pampered Chef consultant. I honestly don't mind if people come and don't buy anything (although it's somewhat rare). I don't like to buy anything I don't want/need but I will always buy a little something at demonstrations. Even if you don't plan on buying anything, go anyway. As a consultant, sometimes I run into a guest who just needs a night out of the house. That's fine and I'm happy to maybe teach her a new foodie fun fact or cooking technique that she can bring home with her.
