Why is the world so stingy?

Stupid chicken rice uncle who gives me chicken rice less than its worth of $3, then when I add char shao and I pay $3.50, he slabs me some measely pathetic amount and it makes me upset. I always give him chance and buy chicken with additional char shao, and see whether he will give me extra char shao if I say "Hello! I want white chicken with char shao" in my sweetest voice, and with a wide big smile. I think he's blind and he's deaf, he never seems to look at me, only concentrates on chopping the chicken. But nevermind, I give him chance.

"3.50 please." He says

"THANK YOU!!" I say. Never say thank you back. Knn. NEVERMIND, I give you chance, maybe you will smile back one day to me and say thank you, MAYBE. But like hello, you're the one who's suppose to say thank you!!! But nevermind, I always say thank you, I'm a courteous girl. I always smile, cause I'm a nice girl. Then when I reach home, open the packet. Knn. Its the same pathetic amount of foood, I always eat like a cow. I dont get myself sometimes, I dont like that store I still go buy, BUT WHY?!?? I WANT TO GIVE THE WORLD A CHANCE. A chance to redeem itself, a chance to be nice to people.... just a chance to change and make this world a better place. Omg, I must be out of my mind.

It's true. Its sad. Why everyone so stingy??? Will it kill you to make someone happy in return? Issit so hard? It's not. I hate customer service, I HATE the people in customer service. All rubbish. All bulllshit. Damn angry cause some of these people dont deserve to be in customer service, they are in it because they want to earn money....and serve customers with the worst freaking attitude. No smiles, no thank yous..... SO HORRIBLE. I hate people who are rude, they are like mean. I dont like mean people. no one likes mean people. They must be people with no friends.

Then there's another experiment I did. Everytime I go to school, I take the lift. When people press the open lift door button for me, I always say thank you! SO i decided to try opening the lift door for people one week and see if anyone says thank you. NOBODY SAID!!!!! WHY IS THE WORLD SO STINGY?!?!?! THANK YOU WILLL KILLL YOU AH?!?!?!

I feel very sad. Its just...such a sad and stingy world out there.
