I recently relocated my plane to a not-very-busy towered field. The plane and towered-field ops are still fairly new to me. One issue has been that the tower usually gives a straight in approach on my initial call up, or soon thereafter. Today I was offset from the runway a bit and just as I started to square up a base leg, tower instructed me to proceed directly to the numbers because of faster traffic behind me. I know the controllers are trying to let everyone get in quickly since the pattern isn't busy, and I am sure most prefer it. Butt being new to the field and the plane, I'd rather at least fly a partial downwind and base. So, other than flying around upwind before I call tower, is there a polite way to let them know I'd rather fly the pattern, assuming it doesn't cause a traffic issue?
