It is silly not to apologise imo, or to make it dragged out of you did. It's a good defensive line: "of course I'll say sorry, it was an accident and shouldn't have happened" and means in future you can make a point of saying *you* apologised for your mistake so why won't X apologise for theirs?
Someone tally up how many times Victoria Derbyshire has asked Zack Polanski to apologise. It's a bit Michael Howard vs Paxo
