A photo of a woman's feet on the armrests of the seat in front of her on an airplane has gone viral after a passenger tweeted out the photo.
It happened on a flight between Long Beach and San Francisco.
The passenger who took the photo says that the woman behind her put her bare feet on the armrests of the seat in front of her. She even used her left foot to raise and lower the window shade.
The woman eventually took her feet down when she needed something from a flight attendant.
