Went to gun store yesterday. I went in at the same time as another person (A) as a third person (B) was leaving the store. While I was browsing B comes back into the store and starts talking to A. B asks if A will buy him a 10mm because his license is expired. A says in a far more colorful way "No way" At volume. They talk a bit more and A leaves the store. B looks at me but I just break eye contact and go talk to an employee. I didn't say anything to the clerk at the time, but i'm wondering now if I should have. Looking for any thoughts on this.
