The LH aircraft in front of my 737 on approach to Hamburg runway 23 a few weeks ago reported a laser being shone at him. I was somewhat taken aback when the tower asked me if I would look out and try and spot it.
He wasn't joking as he asked me after landing if I saw anything. I would have prefered if he had said something more sensible like, caution a laser has been reported by previous aircraft, report if anything seen.
