What I get back is a very stroppy "You WILL get clearance, I'm just verifying your position & altitude".
It's not often a good idea to read too much into the tone of voice of someone with a high workload over RT. I can think of more than a few occasions when an inexperienced ATCO might have thought that I was being "stroppy" when in fact I was just up to my eyeballs in stuff to think about and didn't have time to consider how the tone of my communication would be interpreted by the listener.
