The airport as such is good, no complaints. It is clean, functional and efficient. Shops and…read morerestaurants offer a good range of goods and food to cater for the majority, I would think. Staff are friendly and welcoming.
The big let down is the most unfriendly and often impertinent staff at the security gates. I think they forget that passengers are actually their customers and should be treated as such. Instead, they must think we are a crowd of kids. I travel a lot, and I have never come across anything like it, today was extremely offensive.
As a suggestion, why don't you send a member or two of management as "mystery passengers"?
To get the full experience, pretend you don't understand everything, just as it happened today next to me with an elderly gentleman.
And the behaviour I experienced and witnessed had nothing to do with being busy. We are all busy in our jobs and travelling is often part of it. To risk loosing customers is self damaging and also affects colleagues and many other people. Perhaps a few simple training sessions help.
In particular the crew on T2 from this morning (24th March around 9.30 am) would definitely benefit from an imminent session. Unbelievably rude, unhelpful and unfriendly.
