As said previously, callsign and runway is appreciated in case of multiple runways airport.
As for the rest working in a relatively busy IFR airport, I tend to maximize the use of time for IFRs...
When a pilot comes on with
"XXX tower, good morning this is XXXX , a PA 32, VFR with flight plan from XXXX to your field, presently at four thousand errr five hundred feet err sorry 3500 feet passing.... noise of somebody shuffling the maps... E point estimating your field in ....err [voice of the instructor in the background: 5 minutes !] err 5 minutes, three passengers on board, with information X, request full stop landing, ....errr over "
it is not only off putting and breaks the string of thought, ....
Just a matter of point of view !
