As am I, but my wife, who is very straight but also watches striking women, would have uttered something like, "Oh... my... WORD!" and I would have turned to see what the fuss was about.
Hopefully she would also have thought to offer the woman an escort. I am NOT a big dude, but between the two of us we'd have been a deterrent to anyone but a determined putz. My wife can go into Aunt Debbie protective mode on anyone much younger (and we've reached an age where, let's be real, EVERYONE is much younger) and people do not mess with her.
