Oswaldo you are wrong on a number of points....
The flightcrew cabincrew relationship at BHX is extremely good I have never seen any behaviour that would substantiate your slurs.
Secondly the ground staff are very good as Hand Solo said they can turn a 319 very quickly and we all get on well. I have not been to Man recently but I suspect they are suffering from poor morale and are under resourced on the front line. Lastly there are times when you have to wait as bigger aircraft are dealt with first it makes sense.
