I had a similar situation. FIL had terminal lung cancer that got into his brain. After radiotherapy he wasn’t doing well and was recommended to be admitted to hospital. Told not to go through emergency so try parking in the 10 minute pick up/drop off. … of course its full. So park at the front of the area where it is safe but not technically a park.
Run inside to get a wheelchair and take him and MIL to admissions. Leave them there and leave – all up about 10 mins max
2 weeks later get a fine. Fortunately the council was understanding and reversed the fine once I had explained
