The elevator in my building only lets you select one floor. Accidentally press the one above yours? Now you have to go there first.

Any idea what the purpose of that is? Price discrimination? Abuse prevention? "Well, the ancient elevator did it that way and we want the new one to be the same" backwards "compatibility"?

Probably extremely aggressive nuisance prevention. You could try holding the wrongly selected button down for 3-5 seconds and see if that cancels the call so you can give another one.
