When a person is explaining the way someone else should do things and at the end of their explanation quote "some people dont think like that". How would you takr that comment??

Difficult to answer without being there. But, on the surface, that person could be 'hinting' that you don't think like that, but I don't think so. I would take it as just a smart aleck remark about the person they are talking about and how that person doesn't think like they do.
It sounds like gossip to me, and that is not a good thing. If you can't say something good about a person, don't say anything.
