Have you ever held the door open for someone, and they passed by you without even the slightest "thank you?"
I know it's irritated my before, that's not what I'm doing it for, but it's common courtesy to say thank you!
But there are people we take offense to it.
A man was inside of a liquor store was struck by another customer for not saying thank you! It took place inside a liquor store in Lakeland, Florida. In the video above, you see the first guy hold the door for the second.
Then some words were exchanged and BAM! The guy who initially held the door knocked the other man's hat off his head!
Watch the video above.
