You wouldn't have spotted me based on this. I don't do that with strangers, don't defer, don't agree, nothing. While it might be a good "short-hand" for doms to test the water, you also have to understand that this is also part of the "interview" done by a violent criminal/rapist looking for a mark.
This is common behavior to see if someone is a likely victim. Considering that I wouldn't know if the individual was a dominant or a rapist looking for a target, I don't in any way engage with that.
I also am not "generally submissive" in that, I don't feel compelled to fall under the domly domly power of any male within my range who happens to give off those sparks, even if I'm attracted/drawn to them.
I might banter/flirt, but I'm not going to be averting my eyes or backing down from the challenge.
