Back in the 80's I was traveling from Heathrow to Miami in British Airways. While in Line for the check-in in front of me there were a couple of oil workers with some drinks in their chests, I mean they seré drunk and they wanted to travel in Business with an economy ticket. The station hostess try to explain that it was not possible. They treat her very bad, with very nasty words. Finally they got their boarding passes and leave the area. When was my turn, I tray to appologize in the name of all men. She smiled and told me "those gentlemen are going to Dallas, their luggage to Hong Kong"
