I'm a bit old-fashionned, I'm afraid.... I'm trying to keep up and Lord knows my kids are helpful, but stuff like Boss, Chief, Captain... I can't help being turned off. On the other hand, Man, Dude, Bro, I'm OK.
The ultimate thrill is when I'm approached by someone going Hi, welcome to our store, I'm Andrea, how can I help you ? Wether I'm purchasing or not, I'll most likely congratulate or thank the person on the way he/she approached me. Last person I did that to replied something like my mum always said the proper way to get to know someone is to introduce yourself, so I do that. That's not the way they coach us here, but I do it anyway. She could not have been more than 25.
Now I'll go and find someone to scream at to get off my lawn...
