I know i have read some post regarding this topic, but it happened to me today. I have a message on the answering machine today from "Tommy" and he would like to know what I charge for curbside vacuuming. When I returned his call I asked him a few questions like, "Did you see my ad in the paper?" and he said, "yes". Funny thing is my ad did not cover the area that he allegedly lives in. Second question was have you ever had this service before and he said, "no", but knew what specific kind of follow up questions to ask like, "Do you have a min charge for just showing up and is the rate per minute or hourly. Give me a Break! I told him an outrageous price and he said he would get with his neighbors and call me back. Nice try!
