You blindly follow Spanish ATC instructions at your peril.
I have been put to 'the next Freq' stupidly hot and high and been told to report 6 mile final!
I've have been told to decend below MSA so many times.
Over a decade of operating into Spain and I'm still astonished at what they do, and don't do what they should... Pathetic.
Any area controller in the UK would be shocked at what they get very well paid to do, and do rather badly on occasion!
Does any one wonder why Sim drivers try to pop you into a mountain, I don't!!
Oh, and lets speak to locals in local so as to cause more confusion shall we, sounds like a great idea to me. NOT.
