"Grandchild born safely but Car Parking Charges are..."

My son and his partner was safely delivered a daughter, but mum and baby had to stay in for a few days so my son had to pay the extortionate parking charges after paying £14 for the first day and again on the second he was advised that if he was staying for a while he could get a 7 day ticket that would cost £22.00 and was told that all this is printed on the ticket machine and he "Should have read it"................. Even though he had already paid £28.00 for the two days he was not able to get a reduction for the last day he was there. My son is dyslexic and I'm sure there are a lot of people whose first language isn't English and trying to find security is a mission impossible. The charges for the parents should be minimal as they are in the hospital from 9.00am until 9.00pm in some cases.
