I have an extension in the garage and answered it several times before I got one of those cheap caller IDs. I'd hang up on pollsters so fast. I even had one call back, and ask WHY didn't answer his questions. Before he got much more out of his mouth, I hung up on him the second time.
I had one person call me and I hung up on a female. A male called back and started giving me grief. I found their office number and called their supervisors. I haven’t got a call from them again.
