I found one directory for 1906 where the listing of companies in the rear listed the same address for which the abbreviation confy was used under Confectionary.
> Ancestry.com. U.S. City Directories, 1821-1989 [database on-line]. Provo, UT, USA: Ancestry.com Operations, Inc., 2011.
See pages 934 and 938 of the images of the directory for Confectionary owned by Foster at 114 North Liberty Street.
