Thought I had posted this, but I guess not.

LHR MLL on Xmas Eve. Relatively empty and I was sitting in the no mobile zone or whatever they call it.

Pax sits down on one of the chairs near the windows and starts yapping on their phone in a loud and annoying voice. Briefly puts the phone on speaker to take off shoes and socks. Moves the 'no mobile' sign sitting on the window ledge out of the way so that she can put her bare feet against the windows. Continues to yap on phone.

No evidence of Quantas pajamas though.
