On Valentine's day I was flying EWR-SAN on UA and constantly felt someone banging on my seat back. I patiently waited for the banging to stop but it continued on. When I looked back, the lady behind me had her feet on my headrest. I politely asked her to put her feet down and she simply slid them on the seat next to me. Thinking now the banging would stop, but she constantly moved her feet up and down and bumped into my seat back and forth.

I let it continue for a few minutes and then pressed the FA call button. The FA came and I explained the issue and he asked the lady to put her feet down. She put her feet down and as soon as the FA left, she banged into my seat and then put her feet up.

Soon a different FA walked by and noticed her feet on the headrest and asked her to put her feet down and she replied that she just came back from Europe and she is tired and this is the only way she can stretch. The FA said that she can walk the aisle and she refused. Then a third FA came and asked her to put her feet down and she said that she had a medical condition and this is the only way she could get comfort. After that the FA's didnt bother her.

I had to deal with this for the entire flight. Here you go...
