"Left waiting"

Whilst the treatment received was very good I don’t think it is acceptable for my relative to have to wait outside for an hour to gain access to the A& E ward following a trip out to put more car parking money in machine. I appreciate that the staff are busy and can’t be constantly opening the door, but in the old style department there was a code or buzzer to press which alerted the staff. I think when you are in hospital having your relative with you at a very distressing time is essential. Please have a look at this situation and try and improve things.
