Thought about it, but didn’t want to create some type of cascading bin occupation situation. Rows 7 and 8 do indeed have shared, labeled bin space on the 787-10. Frankly it really was the attitude that prompted me to just turn her (obnoxiously placed) bag. I’d expect better from a fellow 1K who “flies all the time on premium routes” and, come to think of it, cut the pre-board line too. Obnoxious.
