Best Buy Rep Asked Address and Electronics in our house?

At Best Buy the sales guy was weird when I purchased a laptop he took our address, that all seemed normal. Then he went on to ask what other electronic we have at our house and what part of town we are in, almost seemed like he is casing out our house.

Are these normal questions from Best Buy reps? My husband was smart and answered we have an alarm, surveillance camera etc, but was kind of spooky. Maybe I am nervous but think this guy may send some junkies over to steal from us??
