Courtesy, much?

Hi everyone.
I think everyone knows what courtesy is. So I guess I don't have to explain it.
Let me tell you what happened to me today.
First of all, I had Statistics test today. Boy was it 'EASY'. 
I'm saying this because I kinda forgot how to answer this 1 part of the question. I was so caught up in how to draw to correct Venn diagram that I forgot that I actually NEED to answer the questions after it.
When I got to that part, my mind suddenly went BLANK. Talking bout bad timing.
Enough of that and now let's get to the main topic.
As you probably would've expected, the bus didn't wait for us to finish our test. 
IT LEFT. AS SIMPLE AS THAT.
Isn't that just plain rude? Plus, my friend who was on that bus said that there were only a few people on it.
I got no choice but to take a bus to Subang Parade and then take another bus home. 
The thing is when the bus got there, people were pushing and shoving LIKE THERE'S NO TOMORROW.
IT WAS RIDICULOUS!
This one lady kept on pushing me that i felt like cursing her right there in public.
This next thing happened when I was about to enter the lift to my floor.
This girl pushed me like I was a blocking her way.
AS IF. SORRY, YOUR MAJESTY. I DIDN'T SEE YOU THERE.
How rude is that? What ever happened to courtesy? We are Malaysians, for God's sake!
WHATEVER. TMNB.
