Narrative:

We were cleared by tiw tower to circle west to land on runway 35 from our localizer 17 approach. We were also cleared for touch and go on runway 35. During our turn to base; the tower called us; but when we replied; they said; 'disregard.' we continued our circling approach in compliance with the aim when we heard tower transmit to another aircraft on 'short final' for runway 35 as we were turning final. When our right (high) wing was up in the turn; we saw a much faster moving aircraft approaching on a straight-in final approach. At nearly the same time; the tower told us to go-around; which we did; immediately. Tower then further instructed us to side-step left of centerline during our go-around and offered us to return for a low approach. Our training flight required a landing from a circling approach; so I asked the tower for another lap in the traffic pattern to accomplish a touch-and-go. The tower refused; stating; 'unable touch-and-go. Climb to 2000 [feet] and contact seattle approach.' I could sense the anger and frustration in the voice of the controller. We departed the airspace with our training mission failed.the controller failed to properly sequence arriving traffic and allowed us to turn base-to-final in front of faster moving traffic flying a long final approach causing a near midair collision. The controller then became angry and denied us further services. Thus; we felt it safer to leave the airspace than to deal with a stressed controller who had already demonstrated an inability to handle the current volume of traffic at the airport.
