This is a strange question, and nothing to do with the topic of your threat so apologies, do you find the crews on flights to the UK are a little less attentive with service than on flights to Asia? For the past couple of flights now I have noticed that in J the cabin crew to the UK seem sometimes aloof and quite miserable compared to fights to the Far East.
I may just be imagining it, but i swear they dislike the UK sectors!
