You may be faster at the till than I am. I admit I lack practice. You make a good point about waiting in line behind slow customers, though. One of the biggest advantages of the self checkout is the single queue. Having six lineups for six checkouts never made sense.
I am a lifelong atheist. I attend a very progressive christian church where I am open about my lack of belief. They seem to accept me, including the minister. I don’t try to convert them and they don’t try to convert me. I started going because I was lonely and I wanted some opportunities to do good. Their whole theology is about helping people and trying to change the world for the better. The two major precepts are “God is love” and “Jesus has no hands but yours.” They don’t talk about sin or redemption. We have a huge rainbow sign that says “All are welcome,” and we actually mean it. The minister talks about Jesus as a teacher, not as a saviour. We raise money and food for the local food bank, and provide community outreach to people, many of whom have disabilities. We sing. We eat cookies and drink absurd amounts of coffee. I suddenly have so many sweet old lady friends, and even a handful of friends my own age.
