Johhny, its a wind-up. This is just a to$$er trying to cause mischief. There is no way a professional ATC'er would write something like this. On the contrary, I've found the ATC service in madrid has improved considerably over the past weeks.
I PROMISE that I'll purposefully try to give a poor service to every single flight that goes through my hands until Aena gives our rightfully-gained labour rights back to us.
What a sad person he is!
