Someone that kept asking "how are you today?" Because they did not properly identify themselves I immediately suspected a telemarketer.  When I point blank asked "what do you want?" She said that she represented AT&T and that they would be in the area doing a "line check" and wanted to make an appointment to discuss my telephone service. Because a "line check" and selling telephone service are not even remotely connected I told the person they were a scam and told them not to call back.
