Walk ins are a touchy subject. Some people like to see the initiative others don't want to be bothered. Try walking into a flight department asking to speak with the DO about a job when he just laid off half his pilots. Talk about an awkward moment.......

I just meet the manager or director(can't remember which one) of a large bank that just laid off almost all of its pilots. Not really awkward but the guy liked talking to me and would of hired me if there was a position. He is actually networking me into positions that aren't really posted anywhere.
