Didn't know we were un-popular as a group?
They are Air Traffic SERVICES aren't they?
They are here to provide the end user ( us ) with a service.
If I see the need to ask for something then they should try and accomodate me within reason. Anytime and anywhere, that's their job.
So what if I ask on the TWR, if it's not available just say NO.
A waste of a thread if you ask me.
