Don't watch loud videos on your phone at a restaurant. Can't believe this isn't common courtesy anymore

If someone is giving you a ride, you should be ready at the door before they get there. It’s so rude to have someone waiting on you when they are doing you a favor by picking you up

Just because you know someone who does something for a living, that doesn't automatically mean they owe you a discount if you ask for their services.

Don't just show up randomly at someone's house. Call, text, or otherwise reach out and positivity confirm that it's okay before heading to someone else's home.

When you have a complaint with a retail store or business, please remember that the person you are speaking too (or yelling at sadly) is just the one that happened to pick up the phone or is standing at the till. they likely have nothing to do with what went wrong and have little sway in what can be done to help. They dont need to be yelled and screamed at for something they did not do or is under the control of a corporate office/higher up.

What is it about being pregnant that suddenly makes other people feel entitled to touch you without asking.

Don't leave perishable items in random aisles or at the checkout. You're wasting food and driving prices up.
