Thanks Fargoo......
I do take your point on board about them going out of business etc however, they are granted a licence to operate on the basis they agree to the regulations.
That said, I've had at least 7 or 8 instances of this, similar circumstances and just ignored it - but now I just feel it's too much.......e.g. they always get to do what they want, when it suits (although of course maybe not in this case) but when my luggage is 1kilo over - well.......different story
I will keep you all updated,
thanks again for all your valuable help.
