The "flying truckload of housemaids & gardeners back to their home-town" may not be fashionable to you but be rest assured these folks sweat it out as hard if not more for a living than you do.Not all expats in the gulf are well heeled (as you are very well aware) and they get treated much worse
especially if the colour of your skin is of a
darker shade.
Some of these gardeners and housemaids you were flying back to their hometowns would have been going there after two or even three years from home.
A little politeness in the language you use will not do any harm buddy!
