Depends if the question is of something that the potential buyer could easily find out themselves, usually in less time too. That annoys me as a seller, but things that pertain specifically to an individual item, then ya no reason to be an ass
Totally. I have been an ass to people when they come at me and are clearly wasting my time. I had a fancy TLM103 mic that I was selling, it came with a nice hard case that could hold a pair. My add said in big writing and in several places (because I got questioned) that it was just one mic, not to mention as had it very competitively priced. So when someone would ask me if it was one mic or a pair I would know they weren’t a buyer and wasting my time so at times I got snarky for fun. Not necessarily proud of it, but I wasn’t really chasing away actual buyers. I was very polite to those who asked legitimate questions.
