It has happened to me in a couple of variations:
1) Nasty PM after reading my review of another provider
2) "If you see her I won't see you" after I told a provider who I wanted to see.
3) Nasty phone call after a double with her doubles partner and a another provider of my choice.
To the OP and all, I met Jaci at a party (she probably doesn't remember me but she remembers my date and her two enormous assets) I can see the reaction, Jaci is Hot and gives off that very cool and hot Biker Babe vibe, probably intimidates less grounded providers. Anyway fun thread.
