That’s a good question. If they just go in and start kissing, they would be causing a disturbance. If they order food and drinks they would at least be upping business. Either way, it is obnoxious as hell IMO.
Would they really allow them to do that inside the restaurant? It’s unsanitary and disgusting. Chic-fil-a is a family restaurant. They should put up signs that say no kissing or other unsanitary practices allowed inside.
I have never been in a fast food place and witnessed that type of behavior. Not even in LA.
