I hope you don’t use the man on man open mouth kiss greeting that some of the gangs use.

Open handshakes were to show that neither party was concealing a knife or some other kind of weapon.

The open mouth greeting is to show that neither party is concealing an AK-47 under their tongue or lodged behind their tonsils or strapped to that little thing that dangles in their throat. You can't be too careful where not all bikers are part of the 'nicest people.' Or maybe they were just sharing their food like birds do.
