1. When riding the escalator, stand on the right and leave the left open for passers.

2. Wearing headphones in public is code for “Don’t talk to me.”

3. Speakerphone is not made for public use.

4 Never be mean to someone who is serving you food.

5. Always get everything in writing

6. Don't be late

7. Always let people disembark before you embark.

8. When two or more people are huddled around you and are talking in low voices, they’re probably having a private conversation.

9. When someone is walking their pet and you come across them.
Please ask permission before you pet them. Many pets are newborns, or still young, and they aren’t as welcoming to strangers.

10. When in a social situation and you want to speak to someone you find attractive. Don’t overthink and over analyse. Walk up to them and say hello. There is no better icebreaker in the world than a simple ‘Hello’ followed by a smile. Don’t hit on them. Be a friendly new acquaintance. Politeness and good manners go a long way.
An opinion is a very sensitive issue with many.

11. When talking on the phone and you enter into an argument. Please do everyone else a favour and find a quiet or empty corner or place to go to and sort it out. If you are in public, please don’t shout over your phone. No one cares about your personal arguments and no one wants any of it. Hang up and tell them you’ll call back.

12. When you post mean comments, it says lot about you than about the person you are trashing.

13. When someone you know has an obvious change in appearance, e.g., weight gain/loss, bald spot, acne. It is rude and none of your business to comment on it. They already know about it and are feeling pretty bad themselves without you blatantly pointing it out to them.

14. Everyone has their personal space around them. Respect it.

15. Use words more than emojis. Avoid “K” at all the costs.

16. Be quiet when other people are asleep. That means more than not talking — not slamming doors, drawers, etc.

17. Put things where you found them

18. Replace toilet paper after you finish them

19. Holding the door open or pulling the chair out for people is kind, regardless of gender.

20. Never be that person with full cart of groceries in the express lane.

Nice, though not being rigid with them all the time could get well be ur lifesaver .

For Instance:

I could very well choose to obey Rule 2 "Headphones Rule" with you and not alert you you're in the path of a moving bus, right?
