25 min wait from joining the security queue to being able to put a bag on the conveyor belt on an ordinary weekday morning; security staff announcing a further 30 min wait to have a bag checked manually for liquids; and just 2 out of 4 X-ray machines in use.
I understand that this is probably the peak but time waiting in a security queue is time not spent in the shops. Perhaps worth hiring some more staff for the morning shift
