One night, I was delivering a pizza to the last location. A guy opened the door. He was with his friends, and while he was paying the pizza, I heard their discussion about where would they invest 4,000,000 Shillings they earned 10 minutes ago. I just made a glance and saw a sort of graph and figures on the laptop screen. The guy opening the door gave me 1,000 Shillings but the price was only 500 Shillings. He told me to keep the change.

I was absolutely surprised and after I got back home, I took my laptop and tried to recall about their discussion. After 5 minutes, I remembered that they told about online trading. On the trading platform website I found the graphs and figures I saw at the guy's laptop.
