Who is discriminating against expats or foreigners? Have you listened to anything we've said? They're walking into all sorts of positions and are measured by the same standards we all are. Surely you're not still going on about this silly Air Nelson thing? Air Nelson is not worth arguing about, I'm sure there is the odd airline in the UK that uses discriminative hiring practices. I just don't see your point. Don't judge our whole industry by some silly clause on one little company's application form.
Anyway, I feel like I'm flogging a dead horse, so I'll leave you to your infinite correctness.
Oh, and 'some' and 'all' are most certainly not mutually exclusive when used in that context.
Good day.
