I wouldn't consider it bad practice to do as outlined below. I would, however, add an indication in the USER table as to what Type of user it is -- an Administrator, a Client, or Staff. Without such a Type field,
you're gonna have to check all 3 tables to see which it's in. The Type will point it at a specific table.
