Hi all. Is it okay to say 'the hold' in this context:<br/><br/>"I placed <b>a</b> hold on this book on Friday. It still hasn't arrived."<br/>"Oh, sorry about that. When did you say you placed <b>the</b> hold again?"<br/><br/>Since this hold has been mentioned, the definite article is used in the second. Is that okay?<br/>Or is it a fixed idiom: to place a hold, never 'the'.
