@tsarstepan,
I think it's poor English when a group of mixed genders is called "you guys"..
There are perfectly usuable phrased one can use instead of "guys".
I don't really object to it, but it shows me the mannerism of the person using it.
That's of course in a business setting as your example with Boxer showed.
Privately, I think it's no big deal.
I also don't mind to be called "hon" and other terms of endearment. It's a nice gesture and nothing else. One shouldn't read too much into it.
