TOD - The biggest rant I remember having was to our primary care physician when his office installed an automated phone answering system. It was one of those things where if you're this press 1, if you're that press 2, etc. The way they had it set up initially, other physicians were to press 1, others 2, 3, and 4, and, insultingly, patients calling to schedule appointments or inquire about their medical care were number 5. I let Dr. F know exactly what I thought of that and said, "I can't believe I'm the only patient to complain about this." His response was, "No, you're just the most vocal."
After a while, the greeting was changed so that now patients press 1.
