I know it should be easy to open one of those plastic grocery bags but it's always a challenge for me. I just want to lick my fingers but I know that's gross! So, I try to be a nice clean black man and open it with my dry fingers and I can never do it. This really happened in a grocery store in Japan when I was trying to get the bag open. A nice lady was bagging next to me and made it very obvious that she was patting her fingers on the wet sponge. Thanks to her, I learned very quickly about another great tool for convenience in Japan. The wet sponge! Don't forget to talk about stuff like this in the FORUMS! Thank you.
