What happened: Seat, tray table, and floor were sticky due to some prior spillage of a soft drink. I had to wipe all of these down (fortunately I carry wipes) to make them even marginally un-sticky, and my shoes were still sticking when I got to the terminal. (Since my feet inevitably went on the plastic runner near the window which transferred the stickiness.) Sent Delta pictures of this.
Compensation: Form letter, no miles or money.
