unfortunately got to second @bermudatriangle's comments
fly rarely through MAN, and hadn't done so for a number of years, last week Tuesday arrival in MAN T1 was reasonable, needing to wait for stand however despite punctual arrival, and facing a 25mins border queue (queue stretching beyond the queuing system and e-gates out of order).
Then Thursday late evening departure, lights in T1 appeared dimmed (or is it always rather dark in there), and same experience at security, a long queue, which hardly moved. Took 20mins to get through. Followed by running a completely unneeded loop through duty free, trying to get to some sort of window. Departed from a gate in basement of Gates 1-15 building, reached via a staircase leading out onto the tarmac, and some sort of walled/covered walkway brings you into a very provisional looking, but clearly in use for some time, additional (and chilly) departure gate area.
Not sure what to make of these my impressions of MAN, but not blown off my feet.
