I'm sure this is done "quietly" in both Orthodox and Catholic Churches. Probably done because of proximity or lack thereof to ones Church.
My daughter's Godmother's father is a Greek Orthodox priest and we have become very close. He was very honoured the first time I kissed his right hand. I've yet to start any (religious) discussions with him as usually when I see him it's during kid's birthday parties. I've always wanted to ask if he would administer the Holy Gifts to me when I brought my daughter up to the Holy Chalice.
