The scene is a fast food restaurant. There is a couple, probably in their late 20s/early 30s, sitting across from each other at a little two-top table.

They keep standing up to give each other kisses across the table. I am there for about 20 minutes and see it at least three times.

I GET IT. YOU LOVE EACH OTHER.  BUT THIS IS WEIRD.

Just sit down and use that mouth for shoveling in your burger and fries.
