He started to ask the clerk questions about what ammo would work in some gun he had just acquired. He was slurring his words, and his eyes were glassy. The clerk answered the questions, and the guy picked the ammo off the shelf and staggered off toward the registers. This got me thinking: What would be the legal or ethical issues if this guy had been shopping for a firearm? If I were making a private sale and the buyer showed up that drunk, I would balk at completing the transaction. Am I just a paranoid busybody? Would the store or the clerk have any legal liability if something bad happened? Would they even be able to legally refuse the sale? It also occurred to me as the guy was leaving that I hoped he wasn't going to get behind the wheel. He was WASTED... Anyway, I really don't know what to think here. Just thought I'd put it out there and see what anybody else thinks.
