Filipinos commonly greet each other with "Hello" or "Hi" in English, or with "Kumusta" in Tagalog, which means "How are you?" Handshakes and nods are also common forms of greeting in Filipino culture.
I'm a women and personaly I love it when a guy says maam to me. However there are a group of women who are usualywho want to be younger and calling them maam sometime offends them because it can be a sign of old age, like they think only the old people get called maam. But for the most part when you call a women maam they think how polite and thoughtfull, so go a head and use it, you'll get more happiness then ridicule.
