Getting my AC looked at

So I had prepaid for this and they scheduled appointment for today. The guy come out seem nice enough very friendly very courteous very professional. He went out and did his thing and of course he found things wrong what a surprise. Well he came in afterwards to give me the diagnosis and it's going to be about $3,000 to fix it. And I asked him just to give it to me straight. So we did and then he left I went to change because I had to go somewhere else. When I opened my front door in the screen door was another statement The only thing on the bottom was his name and phone number. What I want to know this was his personal phone number. Is was this me being hit on. Because I don't know what that is like.
