I was on a UX flight to Detroit today. During parts of the flights, turbulence was mild to moderate and the seat belt sign came on on a few occasions.

During one the times the seat belt sign was off, I retrieved my bag from the overhead bin, as I was seated in a bulk head. I worked for most of the flight, and when it was time to "prepare the cabin for landing", the seat belt sign was on.
Now, I understand you can't have anything in the bulk head during take-off and landing, but I also never get up when the seat belt sign is on.
After I had put away my bag, the flight attendant told me to stow it for landing. When she came around again, I asked her if she wouldn't mind stowing my bag for landing, as the seat belt sign was on, and I was not comfortable getting up at that time.
She told me I needed to stow my bag, as she was not allowed to handle bags - her words.
At that point, I held my bag up to her, as she was stowing her purse (bulkhead E170), and asked her again if she wouldn't mind putting it in the closet with her bag.
She refused and told me she'd call the captain. She called the captain and asked for someone to meet us at the gate. After landing, as we departed, she went into the cockpit to complain about me, and I deboarded at that time.

I know it would have taken me maybe 10-15 seconds to stow my bag. However, I really don't want to get up when that seatbelt sign is on, and we had already had some turbulence.
Was I being unreasonable asking the FA to stow my bag for me?
