It's not finished!
I am sure many on here have worked or visited offices that were in use but not finished and understood.
Blimey, it may not be great at arrivals, once finished, it may well be absolutely fine. Understandably they have prioritised departures as people spend more time there. Arrivals is even more a means to an end.
I don't think my recent experience was particularly bad, or particularly good....but I just wanted to get through asap so i could get to my destination.
Its never going to be as great as LBA, but hang fire until they say they have finished and pass a more considered judgement perhaps.
