This can be a real problem for people that she was providing a solution for. This can be an issue in the US too. I recently had to have a short procedure and they insisted that I had to have a friend or family member with me and to drive me home. They were adamant that it could not be an Uber/Taxi and provided no information on who could help if I did not have family or friend available.
Several years ago I was scheduled for out-patient surgery at a clinic associated with the big teaching hospital nearby. In the office, the doctor told me the procedure would be performed under local anesthesia. I was unmarried at the time, so I assumed I would drive myself. I showed up at the appointed place at the appointed time. The staffer who was filling out paperwork asked me who was going to pick me up, and I said I was driving myself. "Oh, you can't do that," she said.
Next up was somebody in scrubs, who I gathered was an anesthesiologist. Same question, same answer, same "Oh, you can't do that." Hmmm ... Then the doctor himself waltzed in and asked who was going to drive me home. I again said I had driven myself, and that I would drive myself home. He said I couldn't. I asked why not, if the procedure was to be under local anesthesia. "Well," he said, "It's local plus sedation." I told him he had not mentioned that when we discussed the procedure in his office, and that I didn't have anyone who could drive me. He was adamant that it had to be "local plus sedation" or we couldn't do the procedure. I couldn't drive, so I would have to call a taxi. I told him that made the decision very easy, and I got dressed and walked out.
At the time, my sister worked in a smaller hospital up-state, and did transcription on the side for several doctors' offices. She talked to one of the doctors she worked for who was in that specialty, and he said he always did that procedure just under local. So I made an appointment with him, drove myself to the hospital, and drove myself home.
