It could be a compliment.

I suppose I should be flattered in the confidence of our knowledge and insight, but why would you call a bookstore for information on copyright infringement? Why would you have an option to be involved in copyright infringement if you think a used bookstore is the best place to look for information? I do not know why we get these types of calls, it isn't the first. I also suspect the dress store across the street does not get as many random people walking in looking for information not pertaining to books, or dresses in their case. Isn't it equally likely that any shop on the block will know how to get somewhere, where the bus stop is or where a good place to eat is as we are? It isn't specialized or idiosyncratic information. I am not asking for people to be discouraged from asking us questions but I do wonder why people make the choices they do when they come in here to ask their question.
