MV8 - you're missing the point COMPLETELY old son.......
It's all about treating people with a bit of respect, ie the way some pax talk to the cabin crew is way OUT OF ORDER which is what this post is all about. And try looking at THE CONDITIONS OF CARRIAGE with regards to Carry On allowance and hold baggage allowance. And THEN think about how obnoxious the other pax think you may be, you know, the pax that say "please" or "thankyou", and wait politely for their turn..
It's not about racism or hatred - just REALITY, so less of the PC bull****
