A Karen bit*hing about my Trolley Cart on the Escalator

A Surplus Shop Trolley Cart

I usually bring a Trolley Cart like the one below whenever I go to the Grocery to make it easier for me to carry what I bought, like Yesterday. 

So after Grocery as I was about to go home, I went into an Escalator tugging my Trolley Cart behind me. I'm right-handed, so it was on my right side. When I went into the Escalator, I ended up on the left side while the Cart was on the right side. 

Halfway up, I sensed there was this slim, dark-haired, middle-aged Woman with a little Chinese features who seem to be in a hurry to go up and ended up behind my Cart. 

So I moved the Cart so it ended up behind so she could pass thru. As she passed thru though, she suddenly said, "Dapat kasi nasa Kaliwa yung Standing (People should've stood on the Left)". 

So naturally I was pi$$ed, and called out to her also and said, "Ang dami mong Satsat (You talk too much)". This goes to show that some People just have "Ugaling Baboy (A Pig's Attitude)". 

Yes, she was correct that People should've stood on the right, but then again didn't she even think and consider that I was carrying a lot of things, and that in the end I let her pass thru? 

Some People just think of themselves with absolutely no consideration on the Situation of other People. So Conceited, a typical KAREN, just always thinking about their comfort and nothing else.
