the point of the hand and foot gestures is that no verbalization is necessary! this is a public restroom and talking would kinda ruin the whole secrecy thing.
Yeah, ok, but still something other than footsie or hand signals needs to be done, would you not agree? Playing footsie or making such gestures are not of themselves, illegal. So why wouldn’t nonverbal movements be required before concluding a violation has occurred?
Just my thoughts.
