It was 10 o'clock the night. I was late my office and was standing the bus stop to catch the bus. There was a coffee shop nearby. It was the only shop the neighbourhood. There used to be late guests that shop, for I could see that the owner was not a mood to close the shop.

Then I saw two fells enter the shop. Their appearance looked suspicious. They went and ordered their cup coffee. While they were sipping their cups, I could see them talking. Then I saw both them move towards the counter where the shop owner was sitting. From the manner he spoke to them, I knew they were thugs. After a few minutes, I could hear a hot exchange words. I could also see that the shop owner was self-possessed-. While an altercation was happening, one the two guests whipped up a knife and threatened to stab the shop owner. The other fellow put his hands into the drawer and took what all cash he could take.

I was a dilemma. I could neither go for rescue nor shout because that would be futile. The shop owner was raising a hell a noise and would not allow the ruffians to bolt away with the cash even the risk his life. Luckily for him, the long-awaited bus came there. Seeing the bus, the ruffians left the place and ran away. Before the shopkeeper could recover and cry for help, the ruffians were gone. As already the bus was late, people did not bother to go for the ruffians. I boarded the bus with a heavy heart because I failed to save the shopkeeper.
