I need a unique but not unusual name I can give to people at, for example, restaurants so they can call me when my food's ready, taxis when I order them in advance, etc. Random people who dont really need my name, just something to identify me by. When I say Serafina, they 100% of the time translate that to Sarah. That wouldn't matter, but there always ends up being like four other Sarahs. So I need something that strangers will recognize as a name, but not one that's everywhere.
This came up because I just ordered my taxi for tomorrow morning. Flight leaves at 8am - I'm leaving here at 6. SIX AM! Ugh. Oh well.
