Well done FlyboyAl for doing this, but, I have a small problem with what tuapekastar says here. We all know that a card and box of chokkies is not going to make them do good work. The encouragement to do good work should come from the fact that they have a job and damn good job at that, pretty good pay, an interesting lifestyle that takes them all around the world which should ignite a deep down desire to serve their customers well (which is what they are paid to do), 99% of whom are very nice to them. They are not Gods or Goddesses however a number of them dont appear to have been told of this fact.
These are my personal opinions and if you wish to disagree please remember I am intitled to them.
