Hi Slim Slag;
You are correct that we don't want everything verbatim, except of course runway crossings and hold shorts. However, we do want to be answered and also with a call sign. (Boy is that getting to be hard...) We don't mind wilco with a call sign, however it is much smarter to read back speed, heading and altitude assignements as this acts as a fail safe (hopefully) for pilots miss hearing the clearance.
Oh, as to the writing up of pilots, we don't normally do that, but we will mention transcretions so as to hopefully correct poorly learned techniques or behavior <G>...
regards
Scott
