Sats,
Why is it the Travellers that are immune from the instructions you provide to others? After all they are the outsiders and as such should adjust to the indigenous standards of conduct exactly as you do on Holiday, right?
Or are you like a Football Lout who goes around showing foreigners the best side of British Sportsmanship when you go on Holiday?
Surely if you believe in the Reaching Out thing then it is incumbent upon the Travellers to do the reaching bit first knowing they are the outsiders.
