If we have to resort to subterfuge, so be it.. when it applies to put someone in there place , go for it!’ You handled it great , I’m sorry you were in a position like that and I’m sure I will run across it when the holidays come and my little elderly clients make me the baked goods I scoffed down with gusto, for years.. I would like to be a fly on the wall when you get the chance to tell a non client that harasses you a piece of your mind!
