Has anyone else here pretended to be mute so they don't need to talk?

Has anyone else here pretended to be mute so they don't need to talk? As the title already suggests I do that sometimes. Usually just for buying tickets or ordering food when I am alone. I even played with the idea that I could try that for dating, when I can get the courage for it. It could be a funny experiment to get more comfortable. Have you tried something like that or would you?
