Recently heard on Bremen Information (Germany):
Pilot: Bremen Information D-EABC
ATC: D-EABC Bremen Information
Pilot: D-EABC there is a guy here violently moving on the vertical about 2000 feet up- and downwards. Do you know about that and does he have a permission to do that?
ATC: D-EABC yes, he does, But you have no permission to penetrate his aerobatics box. I recommend you perform a 180!
