This reminds me of the need always to carry glucotabs everywhere, come what may. Your 'goose-stepping' description brought back the memory of trying to get home after, ironically, a clinic visit. I had to get a bus, but remember finding it very difficult to find the cash for the fare in my bag. I knew I was going hypo, but could do nothing about it, and had nothing I could eat. When the bus arrived, and I wobbled crazily to the door, I remember thinking that I was lifting my knees too high. So god knows what I was doing! Fortunately for me, the bus drive took less than 20 minutes and dropped me just outside my glucose-containing house.
