It IS the little things that Emirates do that make the difference, and as for " a nice thing to do", not really, those coins were all just gathering dust, in my office, so better they are put to good use somewhere.
I am also a firm beleiver in what goes around comes around, and although NOT the reason I did it, if someone somewhere at EK takes note, and puts a little marker on my account that I sometimes do nice things, then it can't do any harm whatsoever, can it ?
