Students Are Selfish At This School

No doubt, students are nice (not mean or malicious), but I found that most students are very rude at SCU.
Example1: I booked a room at Lucas hall one day, and there were a group there, I showed them that I booked a room, and they just refused to leave. People also go into rooms without booking, and take their time to leave even though they are over time. People also don't cancel their booking after they are done using the rooms.
Example 2; When I was playing basketball, I had to wait two games so did another guy, then we just rock paper scissors for a spot, he cheated cause he was impatient and didn't want to wait for longer
Example 3: I tutor on wyzant, and I had a scu junior student want to schedule an appointment with her. She wanted in person and booked a room somewhere where. I don't visit frequently. But anyways, I was helping her, I told her the right things except one thing (which I obviously don't see on a regular basis), and within 15 minutes of the session, she wanted to call the session without paying for it. Now in all fairness, I did tell her if it didn't work out in 15 minutes please call it. Wyzant also has a bunch of rude clients, i've had these kind of things happen to me, but this was the first in person one.

Students also talk on the phone really loudly, scream in the halls, never use headphones while listening to audio.

And the evening MBA program is just a whole other story, i'm being treated poorly every day in the program. People are also users in the program

I feel like SCU students aren't mean, but they are very self preserved and selfish, and will hurt someone else just to make sure they do not get hurt. I'd say the good thing though, is this hasn't gotten to any extreme level where it has really hurt me.

I just think the school resembles the city of santa clara in terms of the way people are, city structure ie.
