"Reception staff abrupt"

I called to get a list of medication for my grandfather who I had to take to A&E as he couldn't remember everything he was on. I explained this to the receptionist who said, rather rudely, ' well I can give you a list but you will have to be quick you are tying up the main line'. I do apologise that a 73 year old having to go to hospital was such an inconvenience. I was on the phone for less than 30 seconds!! SO unprofessional
