Oh my god, these are truly revolting!
I thought I'd contribute the following...
Why, oh why, do pax -
1) Change their kid's smelly nappy and leave it in a seat pocket only to be discovered by me during a security check on the turnaround?
2) Ask you to "hang on a minute" whilst doing your clear in, only to place a piece of chewing gum into your outstretched palm?
3) Ask to borrow a pen then give it back to you nicely chewed and covered in spit?
4) Ask you quietly if you have a spare Tampax in your handbag then proceed to tell you the riveting story of how they came on the blob in the terminal toilet "super heavy" and forgot to bring anything?
Any takers?
