I don't. The place bar I usually go to is the place I work though, and most people who talk to me already know me. I probably wouldn't (for the most part) use a bar name unless the guy was freaky or something.

My mom, my sister and my aunt went somewhere onces, and I don't remember their 'names' but my mom said her name was 'bubbles' or something. lol There is a funny story behind it, but I don't know it very good
