The only way I knew the Bush service man had been to my house was when he left our lanai and the screen door slammed shut. I went quickly to the front bedroom window to see what was going on and I saw him getting into the van. I did not receive any service paper that day, nor was I notified in advance that the service was to be done that day. Denise Lowe 1818W, Angelica Loop, Lecanto.
