CS, to me as a pilot and now retired tower controller "finals," although seemingly minor, is one of those little things which trigger a small alert in a controller's mind and makes the controller treat the pilot a little differently. The pilot may not notice but it is there. Of course if operating on speaker rather than headset, everyone in the tower gets to hear it usually accompanied by some comment.
Another example was British Airways pilots adding "the" to the callsign. E.g. "The Speedbird 11." Also hard to get them to say "eleven."
For a bit of drift, would any other controller care to mention any small cues that make you treat pilots a little differently?
