'what is your name' – when I order coffee it is "Lu"

I went into a coffee shop here in Portland and ordered a raspberry latte. They asked me what my name was – really what they want to know is what ‘identifier’ they can call out to let me know my coffee is ready. If you have an easy name like Kate or John or Kathy – you just use that. I have ‘Kaliya’ and really don’t want to explain how to say it or spell it just to get my coffee. So I use my default “Lu”. This was the nick name I picked up while playing water polo at CAL (UC Berkeley) and believe it or not it was a derivative of Kaliya…
