It's disappointing at how expensive and annoying it is to get a test in the US. I went to Germany twice when you still needed a negative test to fly back to the US. Both times, I made an appointment same day at a location a few blocks away from our hotel. No waiting, took about 3 minutes each time, and results were back in half an hour. Also, no charge, even for non-residents.
Self tests were available for about 2 to 3 euros pretty much everywhere - like, baskets of them sitting out in grocery stores. This was crazy to me back when we were hoarding our few at home tests we had!
