Outdated "manners" you'd like to see go away

I say please and thank you and you’re welcome. I say sir and ma’am. I hold the door for a lady and let them go first. I will hold the door for a man after I go in unless they appear older than me, then I let them go first. I thank people for their time when they have been helpful. I like to believe that I have done a decent job of passing these manners on to my kids.

However, I could care less about elbows on the table. I don’t usually take my hat off when going inside - because… why? We almost never eat dinner at our dining table, we are actually fixin to get rid of it and put a sitting area there.
