one day, when you were in the underground garage of a mall, you suddenly felt the ground shake so drastically you lost balance and fell over. The whole mall except you was evacuated, because apparently, it was predicted that a giant sinkhole would open up right below the mall and bury the mall completely underground, and it actually happened, but somehow the mall's foundation was sturdy enough to stay completely intact despite it being buried about 120 meters underground from the earthquake. You scan every shop, every escalator, nothing. It's all completely abandoned, you are the only one here, what do you do?
