I'm putting together place cards for a memorial dinner on May 31st. In general, I'm using the form:
Mr. Andy Clark
I choose to use Andy rather than Andrew because this is a social dinner reception. But the event does have some formal business overtones as I have a mix of corporate, government, and guests at our tables. Should I use the more formal version of my name instead?
--- Thanks, Andy
If you want to use nicknames because it's the right tone for the evening -- do it. Just because it's a place card doesn't mean you have to formalize it. Just write:
-- Robert Hickey
