Haha I can confirm that.
And we bought a bottle of vodka that day. We were going to split it.
I got tired of searching for him, but I heard that they saw him in the bus on the way to hotel.
Our professor was an asshole and he didn't let us go out to find him.
So I ended up drinking that bottle of vodka all by myself.
And we somehow managed to break the elevator.
I swear, I saw two guys in a shopping cart going up and down in that elevator.
