Simile: 'Oozing charm like a runny sore'

Here's a short extract from the novel No Time For Goodbye, by Linwood Barclay:

Paula Malloy was there and she greeted Cynthia like an old friend, oozing charm like a runny sore.

Maybe it's just me, but I don't think the second simile works. After all, a runny sore doesn't ooze charm. Something along the lines of 'oozing charm like a sore oozes pus' might have been better.

Triple mixed metaphor

A great triple mixed metaphor from one of our writers.

Apparently, our publication is "sounding like a scratched record" while the government "holds its sword aloft" and the industry in question "prepares to swallow the bitter pill".

OK, so one of them is a simile – but still not bad for one paragraph.
