I was the Lufthansa 762 Super
In Frankfurt, I wanted to taxi to runway 36
And (Sergio) was controlling ground!
And said me to go to 07C
I wanted to change the runway to runway 36 because it was the largest, and I was taxiing slowly after send to him the (ready taxi to runway 36) and I was waiting for him to tell me something like make 180 or go back and taxi to x runway but NO he reported me immediately!!
