Why didnt you let me remain in the pattern?? and why I was cleared for immediate takeoff?? I was the only one there with Sebastian. After some minutes, I called inbound 16R, and you cleared me for 36L. Remember → Always use only one side of the runway, not both.(example: 16L-16R/ 36L-36R) I announced inbound t&g not landing. The correct responce should have been: Clear for the option Remember to give pattern entries to each and every inbound aircraft or when you want to make a runway change
