TPIM, your experience was very different than mine. Weird. I didn't get any option of a "rapid" test. Since the normal test is basically 1 day turnaround right now, I don't see a benefit to the rapid option.
As for the people saying there's little incentive for an individual to get tested, I agree that's true for some people, and something I said a few months ago. If you are a single healthy adult, getting tested doesn't change your life much at all. You are still legally required to isolate while you have "core symptoms" regardless of test result.
For myself, a positive test would have me re-evaluating some of my normal behaviors, like visiting elderly family who live alone. It would also mean different behaviors for my family. That benefit may not be useful to others, so I can totally see why people would not bother getting tested.
