Sit at the front and ask for after landing. There is usually pressure to get people off onto buses or through locked doors, so there is not a lot of time as the cleaners and caterers want to get stuck in, and the pilots have checks to do, paperwork to fill in and walkarounds/refuelling to do. Don't hold it against the FR girls- they work very hard and are always knackered. They're all called 'Ludmilla' too!
