What small act do people do that causes you to instantly not like them?

1. Mobile games with the sound full blast. Seriously, come on.

2. People who think it's cool to use as few words as possible. I get customers like this at my bank all the time: Me: Hi, how can I help you? Customer: Box. Me: Uhh...what kind of box? Customer: Safety deposit box. Me: Uhh...what about them? Customer: I need it. Me: Uhh, you need to open a new one or get into one you have? Customer: Open one. Seriously, it's not like we're texting here. You have a voice, SPEAK IN FULL GOD DAMN SENTENCES.

3. People that have to turn every conversation into a dick measuring contest. If I mention that I'm tired today because I only got a few hours of sleep last night and they reply with "You think you're tired? Well *I* only got one hour of sleep last night!" I know people that always have to try to one-up anything you say and those people are the fucking worst.

5. Litter, You are a true asshole if you not only do not pick up after yourself when you go camping or picnic somewhere, but also carelessly toss trash just anywhere instead of taking that slight effort to throw it away proper later. It just shows you have no respect for your city, other people's property, public parks, or nature in general. If you litter I just automatically assume a selfish and scummy person.

7. When you're in a fairly open, sparsely populated area and someone enters the space and stands annoyingly close to me. **YOU HAVE THE WHOLE GODDAMN SUBWAY PLATFORM TO STAND ON AND YOU WALK ALL THE WAY OVER HERE AND STAND 2 FEET FROM ME, WHY**

8. Humble-brag. Just stop it, we all know what you're doing.

9. Telling stories that never happened. Especially when they're blatantly lying but they expect you to believe it. Also, being rude to their parents for no good reason.
