A story based on @xpilar's digital image: Black Friday, or something with a discount.

Andrew was sitting on the balcony of his room at the Casiopeia Hotel when he heard a loud noise followed by the vibration of the building, he raised himself, afraid to fall to the floor.

He leaned on the pirila and began to look up the street, towards where the strange rumble came from.

Suddenly, the source of the sound became clear.

A huge wave similar to a tsunami rushed down the streets of the city, but when it reached the walls of a huge supermarket, the wave spread and calmed down...

Andrew went into the room and called the porter.

What's happening? In the travel agency, no one told me that this planet is dangerous for life and there are kaktaklismy here! - He turned to the employee of the hotel.

Laughter from the other side of the phone wire made Andrew pretty nervous.

No sir, it's not a flood, don't worry, it's black friday! - I heard the voice of the porter mixed with grunting, apparently, he was trying to hold back his laughter.

What is Black Friday? Andrew hesitated.

Supermarket sale today discount for an extra hydrogen atom on this day twice a year a starship from the planet Deuterium arrives and heavy water deuterians cannot miss the opportunity to spend a couple of bucks on an extra hydrogen atom - said the receptionist and hung up.

Andrew ran to the balcony and began to peer into the body of water and realized that it was not water but a lot of translucent creatures which now lined up in something that looked like a queue and were waiting for their time to get something at a discount in supermarket.
