Hi, I think that these tips would be overall very helpful. There are a couple tips that I don't agree with and would either modify or take out. First, I guess I don't really understand why someone would be offended if you asked them if they could use chopsticks. They aren't widely used in the west and a lot of people really can't use them well. For the part about coming up to someone and trying to practice English on them I would modify it a bit. I think it is perfectly fine to try to start a conversation with someone who is just sitting there "resting". If they seem disinterested, then you can just wrap it up real quick and move on. I do agree that if someone is reading than you probably shouldn't interrupt though. Anyway, great idea and tips!
