Instant Waterfall

I was at a customer's place in Kelana Square today when there was a sudden rainstorm. I did not notice it was that heavy until I saw the waterfall which flows on the glass of the entrance doors.

Nice waterfall effect but the puddles are getting bigger

Water from upstairs overflowed. Pity the guy (left) who was trying to clear the water

Coming up to the floor above, the place was flooded
