My last T2 experience, some months ago, was also mayhem with chaos airside with queues & nowhere to sit & worst of all, no toilets remotely anywhere near clean,with queues for the Gents as bad as the Ladies.
T1 experience last month, vastly improved, although having to taxy back onto stand as the agents had "forgot" to offload cargo from the previous flight kind of makes you wonder how many cock ups get through without being noticed
