Im a little different to most people in that it dosent bother me to much what there wearing (I once had a guy ask me for a job after he finished laoding catle and was still coverd in ****) I look more at personality and how they are going to fit in.
I think it has a lot to do with confidence ,if some one cant walk up and say hello my name is such and such with out breaking into a sweat and stumbling through thier words how are thay going to tell a 130 kg truck driver that is pissed that he cant get on the aircraft because he is intoxicated.
well thats how lokk at it anyway
also i cant teach someone not to be shy but i can give them a lesson on how to iron a shirt
