So, just that - as a fairly regular flyer it seems that some people behave as if they were in their own living room and don't give a toss about their fellow passengers.
Examples - sat next to a young man who decided to take off his trainers throughout the 3 hour flight - only realised when I wondered what the hideous smell was, old man trying and really struggling to put bags in overhead locker - no-one near him offered to help so in the end I did even though I was a way behind him, people barging off the plane when it lands without letting people in front off, the way some people speak to cabin crews really aggressively as if they are their personal servants (woman kicked off because her card was not working when she wanted to buy cigarettes...) people kicking backs of chairs, chucking rubbish and food on the floor, being sick because they have had too much to drink (and Ryanair crew clearly reluctant to clean the aisle so people went trudging through it) ... quite a long list in all honesty though not all on same flight thankfully!
Lots of examples of rather gross and thoughtless,unkind and rude behaviour or maybe I am just getting old and crotchety (yes that as well)
