I would find this one confusing "Cessna 1234, where did you say you wanted
to go?" It uses the tail number which is enough but indicates that the
controller is still trying to figure out what to do with me. I would
question whether that establishes radio contact to enter the Class C.


Radio contact has been established. You have pemission to enter. It is not an
entry requirment that the controller know where you are or where you want to
go. See and avoid is not superceded. While it is sorted out, you may proceed
in.
