I don't use clipless pedals on my errand/commuter bike for a couple of reasons, the main being I like to wear whatever shoe I feel like for the errands I'm running and because it's easier to walk in "normal" shoes. The other being that cleats can damage flooring and walking in cleats could possibly damage the cleats themselves. We don't wear cleats in my house for this reason and I try to show the businesses I patronize the same respect.
