no one seems to have mentioned that 10% of the population carry hepatitis here, plus its rife with foot and mouth disease. I flew with a cabin crew the other day who was upset about crew control not understanding that she was in quarantine with her kids with foot and mouth and they asked if she could get out of it! Think of any number of unfriendly diseases and you will want to have your own cup. Couldn't give a Shiiiit about the color of a cup but quite fond of my nuts don't want them in specimen jar just yet!
