Bad day

As the title suggest. It's not a good day today.

Went for lecture and couldn't understand what the lecturer was talking about.
He just sped through the lecture.

After lecture, I went to take the MRT to Mount Faber Safra to collect my e-mart stuff.
While standing on the escalator, the escalator suddenly stopped!! Scared the hell out of me!! Fortunately I held on to the railings immediately, if not I would have rolled down the long escalator at Kent Ridge MRT! AND DIE!! Thankfully there wasn't any elderly behind me or on the escalator, it would terrible if they fall and worse still roll down and knock everyone on the escalator!!!

At Mount Faber, I was greeted by a staff whom I thought was friendly. It turned out that she was more grumpy than me!
I just asked her, "Miss, if my shoe size is not correct can I change?"
Any normal sales person or cashier or retail worker would say yes, within how many days or simply apologise and say no. But this particular staff said, "didn't you check your shoe size before you ordered online?"
I'm like 0_0? Check online? Like how? Put my feet on my computer screen?
(Yes, I know my shoes size but some shoes have different cutting)
And she added,"that's the problem with you all, don't want to check before you order."
Can't be bothered with her anyway. Poor service attitude!!

I hope I can wake up from the right side of the bed tomorrow!
