I always found that placing one's hand over the heart and gently bending forward (not far) worked quite well when dealing w/ those who didn't shake hands. Even Emirati women did this w/ strangers at times. It's akin to what the Japanese do. "Pleased to meet you" but w/o the body contact. I've been through that, too, so don't worry. Some of my students introduced their older siblings who were in the last years of university...quite awkward to be left standing there, but they understand that you're new. Now you're ready for the next meeting!
