h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Okay, now, I understand the logic and emotion behind public displays of affection, heck I'm guilty of performing them! But, isn't there a line which shouldn't be crossed? For example, I am hanging out in my aformentioned fav bar when these two couples walk in , nothing too odd about them except they are bikers in a normally non-biker hangout. One of the women decides she needs to use the facilities, so she tells her man who promptly cleans her tonsils. My friend, Andi, looks at me and says "If that was a kiss to go to the bathroom, I'd hate to see a kiss good bye." I agree, and say "She wouldn't have a face!".
Now, I like PDA. It's fun, but taking it to the point where you should really be some place more private is totally different and kinda disresepctful. Noone else really wants to see your tongues, so please keep it to yourselves!!
