A friend of mine was having a discussion with a contractor working in his yard about something he was entirely unfamiliar with--natural gas powered grills. Having never researched the topic before, he was a little unnerved later to have Facebook serving him natural gas grill content ads. (still having not ever google'd them or anything)
