I feel for your frustration - and yet, perhaps more tolerance has to be given for Doctor's and carer's visits, no? Where will the carer park if you ever need to be cared for??? However, no excuse if there is sufficient space and carer does not ensure she uses it as carefully and fairly as poss. Mind you- they have hugely full time-tables and have to rush from one client to another, so parking carefully may not be priority. I'd be very polite, big smile, and just try one more time to ask calmly, quietly and saying you understand they are in a rush, etc. Then I'd call the agency as you have the name from her badge. And then call the Council if there is no improvement.
