CIGAR TIPS .... GUMP
Done
I pulled up next to a brand X the other day and waited patiently for the aircraft ahead to takeoff, the pilot head down and intently doing something on his magic screen. He was unfortunately blocking the taxiway for runway access. Finally I made a call asking "Aircraft holding short, will you be ready soon?" He physically jumped in his seat. He taxied off to the side and I took off. Keep it simple, make it quick.
Cheers!
