Here's my idea for an SCP
Its a set of Stairs and an Escalator at Site-19, the Stairs and Escalator are sentient an can both speak English, Spanish, French, Russian, and Chinese. Although the Stairs can speak more fluently.
If a human were to go on the Escalator it will communicate to them and say "which do prefer, Stairs or Escalators?". If the subject says Escalators, the Escalator will move the subject to their destination and will have a friendly conversation about why the subject made the right choice and should never take the stairs if there's an Escalator nearby.
If the subject were to say stairs the Escalator will move backwards at fast speeds and become verbally hostile shouting insults and profanity's at the subject and say that all stairs should be replaced and outlawed.
If a human were to go on the stairs it will communicate and say "what do you prefer Stairs or Escalators?". If the subject were to say stairs, the stairs will begin to laugh and have a friendly conversation until the subject walks to their destination. The Stairs will never mention Escalators during this conversation.
If the subject were to chose Escalator the stair will let out a sigh and say "oh of course I mean what else will you fleshy meat shacks ruin again, now you don't even need to move your legs to do anything". The stairs will than collapse preventing the subject from getting to the top of the stairs. One hour later the stair will reform to its previous formation.
