Giving your loved one a kiss in public is fine, but some people need to know where to draw the line. Having long make out sessions, groping each other and stuff is just wrong in my opinion. For one, I don't think little kids should have to see that and I doubt their parents want that or want to have to try and explain that to their kids.
There's a time and place for that and it's not in a public place, like the old saying goes, GET A ROOM!
