In order to make any money, you have to sit and stare at your phone, holding your breath, waiting for them to call/text. If you miss their call and don't get RIGHT back to them, you go on their "unreliable" list and they don't call you again! They actually expect you to be on-call for them for $25-30/appointment!!
I was once called by a guy named Ronald who was so inarticulate I could barely understand what he was saying. I accepted the assignment he offered and hung up. Well, right after I hung up w/him, I ran outside to secure lawn furniture and other things, because there was a tornado watch in my area. It took me apprx 40 mins to do this and then change out of my wet clothes once I came inside. Inarticulate Ronald must have called back while I was outside, but I missed his call, so he CANCELLED my booking and wouldn't take my call when I called back. What a joke.
