Probably because of your language.
People have to remember the holiday is over at the departure airport. They have been living in tropical temperatures for 1 or 2 weeks and it is time to come home......normal temperatures start on the aeroplane, and Gatwick in November isn't really the time or place for shorts and flip flops (why can't they wear shell suits like everone else?). Do you know whole families have been observed in family matching shell suits? Oh the GBP (Great British Public) on its annual outing! Verily I do believe they should not hand out passports like confetti- but as they hand British passports like confetti to tribesmen from places 4000 miles away, I suppose the GBP itself should not be denied. If they stayed in GB and bred more, we wouldn't need so much free and easy immigration.
What was the question again?
