I don't know who Susan was . . .but I am guessing that she was not lazy at all.
I am guessing if she had a rotating surface named after her,
she was very, very busy and needed to find a way to be more efficient.
All I know is I love painting on these surfaces.
And I love using them in my kitchen . . .or bathroom . . .or family room . . .or ???
I'm sure Susan was a multi-tasker - so the (un)Lazy Susan can be a multi-tasker, too.
Don't you think?
