Regretevator!

—An elevator which kept reaching random floors without any end, each one more rarer than the other. Until at one point the elevator stopped in 'Subway', when the doors opened you saw a person with saturated colors in their clothes, letting you hear a happy sound in their party horn. They came in without saying anything and after a while they decided to talk to you first.—

"Hyelo!!! Do you usually come to this elevator often??"
