Can Anyone Solve My Original Riddle?

Hey everyone, if you were an early follower of mine, you would know that I made some riddles and saw if anyone could answer them correctly.

This riddle was made by me, Hive account@jbreezy, submit your answers in the comments and once someone gets it right I will post the answer with the person’s name who got it right.

The Riddle
A man walks into a room, there are no doors, and no windows in the room. The walls, floor, and roof are made of concrete. The man doesn’t like the way that the room looks, so he walks out.
How did he get out?
