Yep, I'm with "tired" on this one. "N.sky" raises a valid point, but a question is not an instruction and visa versa. In a busy R/T environment, it is essential to strike the right balance between clarity and brevity. I would never wish a pilot to feel inhibited in seeking clarification, but please only if reasonable grounds for doubt exists. Let me cite another example (not a moan). ATC clear pilot for a Visual Approach. Frequently, the pilot will then ask if he may descend. Quite unnecessary. If ATC require a level restriction, it must be specified with the clearance. If you are asked to report your speed to XYZ, then please do just that. If a particular speed is required, it too must be specified. Hope this helps.
