How would you feel about this business related situation?

I own a small pet sitting business with a few employees. Whenever a new client calls to establish service I am the one who goes out to do the consultation. Yesterday I ran into a very uncomfortable situation. I went out to do a consult and when I arrived there was a car in the driveway for another pet sitting business and a “gentleman” was coming down the walkway from the house. I assumed it was the owner of the other pet sitting business and that their consult had run long. Sometimes prospective clients will interview more than one sitter and really that is no big deal, I welcome the competition. However it turned out that the guy coming down the walkway whose pet sitting business was the owner of the house who called me for the consult! I really felt trapped at that point because I am out of my car with my paperwork in hand with this guy greeting me. I am really upset that he did not tell me upfront that he was a pet sitter and I am dissapointed in myself for not speaking up and saying something. He got me there under the premise that he needs care for him and his wife’s cats in June. I am left with a bad feeling about all of this. I honestly think he was drilling me for information. He seemed nice enough though but the fact that he didn’t tell me upfront that he owned a pet sitting business just seems wrong. I feel like I need to say something but I am not sure if I should and if so what??? Please help Jellies this is really upsetting me. :(
