Jim - where I come from (South Africa) we also call it supper. The informal meal that we have at home in the evenings we call supper. I guess that goes right back to biblical times with Jesus and his disciples - The Last Supper&#33; (Informal at home) A meal at a restaurant or formal dinner (think cruise) we call that dinner.  We have learned to just call it dinner here.... I wasn&#39;t even aware that some Americans also call it supper too.
