Our GP surgery was very organized. My wife and I were given appointments 8 minutes apart. We walked down together and my wife walked in while I went for a walk around the block to burn up a few minutes. Walked in and a special desk had been set up with a person just for flu jabs, checked me in, and before I could take my seat my name came up on the usual monitor to go through. All doors open so no touching anything, nurse gave the jab while standing up, I continued out through the back door which is normally emergency exit only and I was out of there to meet my waiting wife within 5 minutes.
My wife's sister in Edinburgh had an option for in-surgery or drive through so she opted for drive through and never had to get out of the car.
