In Japan, we buy packs of these pourover single-serve coffee filters prefilled with coffee to use in hotel rooms. On Amazon, I buy boxes of empty single-serve filters to bring when traveling, filling them with locally bought ground coffee. Here, I’m using one left over from our recent trip. Just one example of how travel changes behavior. A more significant example is the ubiquitous washlets in Japan. We liked them so much, we installed TOTO washlets in our home.
