We can argue cutoff times for morning-afternoon-evening- night all day long. Given info on this site and from the OP, seller was in NJ (looks at map), which would be EST. When telling me he'd pay me in the morning, he could had informed me of his current time zone. Which, he has not chimed in if that was. Even if he was in PST, if you greet someone with "Good morning" at 11am in the workplace, I'll take a guess and say they're gonna give you a strange look.
We can play the "what if" game all day. I'm not a scammer, and am accountable for my actions. Both sides of the case have been presented along with the facts (none conflicting), let's hear a verdict so we can move on.
