"Rude X-Ray receptionist spoilt previously great..."

I've had superb service from the oral unit at this hospital, who always push for (anonymous) feedback on every visit. No surprise given my very rude experience at the Radiology department that there were no customer feedback forms available. I arrived just in time for reception to open. The two people in front of me were rudely told they'd come to the wrong department, despite them having been directed there by other hospital staff. I moved forward and since there was no "Hello" or "What can I do to help?" I said "Good morning" handed over my reservation notice from my GP. "What the hell am I supposed to do with this?" she snapped. It had my appointment time on, but not my name but there are far more polite ways to ask someone what their name is, or even just to check the appointments diary. I didn't get the lady's name but I don't understand why hospitals employ staff who are so rude and obnoxious to people who are clearly nervous when visiting hospital. Fortunately the young man who actually took my X-Ray was much more polite.
