The image shows two elevator doors with identical exteriors. On the left is a traditional elevator with a metal sliding door. On the right, what appears to be another elevator is actually a flight of stairs behind the door, which is open. These stairs present a hazardous situation, as someone might mistakenly assume there is an elevator there and could potentially fall down the stairs.
Above the images, there's a caption that reads, "The owner that did this deserves a special place in hell." It's followed by the word "Sarcasm," which suggests that the message should not be taken literally but as a critique of the design's deceptive and dangerous nature.
