Utterly ludicrous storyline and character (Sheila).
Norris would NEVER employ someone straight away and without checking references. All his life on Corrie has been one of attention to the tiniest of details - the "interview" was completely out of character.
As for Sheila - does Corrie really need another "comedy" female. Especially a not very funny at all "comedy" female. If this was the case, he may as well have taken on the awful Teresa and saved the producers a salary.
