Nick and I went out for an indian with a woman and her husband that I had met in some classes I was attending. She had pounced on me as she didnt drive and we lived close by, I couldnt shake her off. All was going well although a little difficult as we were all newly aquainted. The bill came -she passed out -ambulance called - Nick paid the bill and we never saw them again :-) smacks of only fools and horses, extreme but true! I'm sure she was ill, I mean you wouldnt pretend would you. I was happy never to see them again, no more lifts etc! Dont get me wrong I would drive miles in the wrong direction to pick someone up/drop off and I have, but when you know deep down that its about what you can do for them rather than friendship, its not good. In answer to the question, the fairest way is to divide the bill up would be according to who has had what, however, that is not the best way -50/50 for me everytime!
