.......Having a sense of humor is one thing and so is being professional on the air.
And in my opinion Boston John successfully does both.
I'm not in ATC but I'm on the air professionally as an emergency services dispatcher, something I've been doing for the last 16 years (and still waiting for it to become a 'job'). I truly believe from listening to all the Boston John archives here that he truly loves his job as well.
While dispatching PD/FD/EMS units doesn't have the same repitition to it as a tower controller position does I do have my own 'style' while on the air. It doesn't delay getting a call out, it doesn't offend anyone (that I've ever been told in 16 years anyway), and it's not juvenile or immature. My officers (and FD and EMS members) have told me they enjoy when I'm on the desk.
I can't, don't want to, and could care less about that pilot. If he was that callous and rude to make that statement then he has a lot more to learn about how to deal with people. I wonder what his PA announcements to his passengers are like...........
