Stop in for a cup of coffee

So on another subject.
You sent a guy a pm. 10 minutes after he posted, then another guy asks to be second in line.
And the seller sells it to someone who never posted?
With a response I should have held an auction.
W TF. That guys on my do not buy or sell to list.

"Common" courtesy is fairly uncommon.

How's that work in the real world? Pick the 8th guy in the queue randomly and sell him the last donut? "Sorry folks, we're out"
