Traveled this week DFW-TPA in seat 1C. The guy in 2C had an "active bladder" and each time he hopped up, he grabbed my seat back to hoist himself up. Pulled hard enough to recline my seat without me pressing the button! You would think that the scowl that I gave him would have been enough to deter him, but no...... This is a pretty common behavior on flights, but the repeated performances this week really struck a nerve. Am I being too sensitive?
