I give a different name. My problem isn't so much that no one knows how to say mine; it's that no one knows how to spell it, and since someone else reads it, they generally fumble the totally weird series of letters the other barista wrote down. So I started to think of it as less about providing my name -- I don't care about fake familiarity -- and more about providing a uniquish identifier. So I optimize for that: pick a name that everyone knows but few people have. "Art" works pretty well.
