Truth is beauty
Several thoughts on your comment:
1. It might be more appropriate go to art school to learn how to be a better photographic artist, not to a camera store. I've yet to run into a highly experienced/published or well-employed photographic artist working at a camera store. Most are selling gear for a reason. 😉 (NOTE: I'm sure there are exceptions!)
2. If the question was asked in a different way-- more appropriate to the situation, the answer might have been different. What if the question was, "I have a Pentax K-1000 and think better equipment might help he achieve results like that guy who's art is featured over their in your gallery. What do you have, or what kind of equipment should I consider looking for?" What if the question was, "To get that kind of depth of field, which would be a better film to try: 100 ASA or 400 pushed to 3200?"
3. The question asked would have been more appropriate, and probably accurately answered, at the gallery opening. Even more obtuse questions like, "Is that bokeh I see in those two prints?" probably could have been addressed.
Had these three points been known to the OP a totally different comment would likely to have posted and you might not be assuming that the clerk "had a bad day" or was "doing his job poorly". 🙂
You're in your right to believe the man had a wonderful day, and did -for that customer's question- a great job.
Cheers,
