I would guess it's stupidity. We have a mindless segment of society now. They're rude as hell talking and playing with their phones in restaurants being loud and obnoxious.....in fact, Kitty and I were out couple weeks ago at her favorite Mexican joint. Guy right behind us was talkin LOUD on his phone and had it on speaker. I asked him politely over the back of my booth to please go outside so we could eat in peace. He said and I quote "get fucked old man". Now, when I was younger, I was a tough customer. I'm still a big guy and when I get up, I can be imposing. Which is what I did. Turned around and looked him dead in the eye and said "follow me outside and say it again" and I proceeded to the door. He got up and stopped me and apologized and said "we ain't gotta do all that". He was a little pipsqueak, but I'm still glad he didn't take me up on it. I would have to hurt him right off the bat, because if I didn't he would have hurt me. I told him "fine, but there's no need to be rude and cuss your elders. maybe remember that next time". He actually said "yes sir" and went outside and finished his call. I'm getting to where I put up with that type thing less and less. It's probably gonna get me in trouble one day.
