There was a discussion on Reddit about things that were considered totally normal 20 years ago, but are completely frowned upon today.
Here are a few of the best ones . . .
1. Calling someone just to ask a quick question.
2. Asking to check out the cockpit during a flight...and sometimes getting to.
3. Smoking in restaurants.
4. Not having a cell phone.
5. Writing a check at a store.
WHAT ELSE COULD YOU ADD TO THE LIST??
