They'll be thinking "what the fuck happened the the runway?".
There is no 28R, you can have 27R or 27L (or alternately 9L or 9R.
Back in my youth (about 50/55 years ago) they were 28R and 28L/8R and 8L. Don't ask me when that were changed or why.
What I do know is the supposedly defunct (1950-2010) Cranford Agreement stilll ensures that there are no takeoffs from 9L over my house, only landings.
Addendum after Net Search
Apparently the change from 28R/28L and 8R/8L was to prevent misunderstandings due to the common '8' in both directions
Rumour has it that some dumb TAROM pilot tried to land into take-off traffic. His error was, apparently, detected early enough to prevent any accident. This is only hearsay, even the spotters of my generation can't confirm/deny the story.
