I laughed a little as I read some of the "Worst Of" lists because I think we can see some of the same tactics across them - super defensiveness, trying to get YOU to talk, and to talk slowly. I wish I could remember all their names. In no particular order, I find all these characteristics terrible in readers...
First are the psychics who did the "tell me your name, say it really slowly, and their name, really slowly, and birthday, really slowly, etc. etc., as slowly as possible so I can REALLY tune in" or did that thing where they kind of peter off or start talking slowly themselves. Jennifer Moran did this. I just went on Keen to try to find the name/listing of the other reader who did this to me (I'd recognize her photo) but couldn't... maybe she's gone, which is a good thing.
Second are the ones who are all "I don't know much about that" where "that" is a job search, or relationship, and they're trying to get YOU to burn time by talking. Eli Casey did that, and he sent me rude and harassing email after I hung up on him.
Third are the ones who are rude, as in they're taking calls while cooking or driving, and it's obvious they're not talking to you. Tina Bliss did this, and there was another reader (again, can't remember his name but would remember the profile pic, he was one of those who would take his profile down and the reappear a few days later) who I called who was eating chicken wings or something disgustingly chewy and sucking sounds for the minute I was trying to talk to him.
Fourth are the ones who just. don't. take. a. breath. So you can't edge in to ask a clarifying question, get them to stop the line of reading they're on to "refocus" them (ha! as if they were really "tuned" in to begin with): Dalya, Maharani.
Fifth are the ones who compare your situation to other clients' situations, or tell you about other calls they've had, or about their personal issues. I don't want to know! Some readers will send a few minutes to make up for having used your time for personal stuff, but I found this annoying: Dalya, Samantha's Insights.
Sixth are the ones who start talking about the phase of the moon, mercury retrograde, or the alignment of random star to your rising sun. Again, fascinating, but when I'm interested in astrology, I'll get on that myself rather than have someone burn up my time on the phone with an astronomy lesson.
And lastly, the ones who just aren't psychic or empathic. They are just there on the phone, trying to make a quick buck. Ugh.
