Hmm, I think I was there...must be blind in one eye and can't see out of the other! Either that or the sign fell off!!
It's not that so much anyway as that you're the 'odd one out', if it's the wishes of your customers, how come the same/similar customers don't make the same wishes at other airports, or do other airports just ignore their wishes? Who knows.
Anyways I'm pleased to learn you are in fact friendly and apologies for missing the rather obvious signage!
