Thanks for the responses and noted on all of the above.

Issue is relatively straightforward and minor. My wife and I were in the exit row (A319), boarder first, put our carry-on's above. Not surprising, as someone who flies enough to qualify as a GGL, I'm really good at efficiently packing an overhead bin. I did just that. All bags were vertical. Coats were placed entirely on top, etc. You couldn't have done better.

It was a full flight. There were storage issues. FA came by and just started grabbing our coats and shoving them back on top of other people's bags. I politely said, "I would prefer if you could leave our coats on top of our bags." In the most condescending Kindergarten teacher voice (while placing his hand on my shoulder), he says "we don't always get what we prefer. We need to make room for other people." Of course, once he realized how well it was all packed, he put it all back to the way it was. But no apology or anything.
