"Asking about religion"

All the personnel I've dealt with today was very polite and sufficient. We were seen and treated very quickly even though uc was very busy. I just cant accept questions about my religion especially asked in front of so many people. I can't see any relevance to my medical needs and no necessity to ask about it. Does my treatment depend from my religion? I couldnt even answer that I decline to answer which I found absolutely appealing.
