You are right, I was talking in general terms. And vice versa, the welcoming attitude to non-Russian by the Russian True Orthodox is not something that NECESSARILY happens.
Also, it is very true that the attitude towards us perhaps depends on how we behave, I must admit while I was very interested in the liturgics and chanting, I wasn't interested in greeks, all I wanted is to attend the service, get some ideas for my paper, and leave right away.
After the dismissal an altar boy came and told us that the fathers welcome us to the "cafenio", Vova immediately accepted, and I had no choice than to smile and say "Very kind".
I was as usual, very formal, polite and respectful, but the greeks were not respectful at all. I said things like "how do you do" making eye contact, with a gentle smile, and keeping my distance, I got reactions like "Hey!!!" with two or three kisses, grabbing me by the shoulders, and talking to me in a familiar way.
One of the worst reactions was that of a lady, who after asking me how old was I said
"No!!!! you can't be serious"
"yes I am ma'am"
"OH HO HO HO HO HO, you are a real baby face, come come with me"
She grabbed me by the arm, and took me where some persons were, and said things in greek, and I got some other reactions, a woman pinching my cheeks and saying "You'll do a lovely son in law" other man hitting my on the arm with his fist saying "ohhhhh! We'll get a good greek wife for this adonis" etc.
So there goes the theory of you show respect, you get respect. I showed respect, and I got tons of disrespect.
It was one of the worst culture shocks I've ever had.
