No please fill me in. Is cash more or less disgusting than the upholstered bus I ride to work every morning? More or less disgusting than cured meat?

I work in a radiology department. You would be surprised how many people store wads of cash rolled up in their underwear. One patient in particular comes to mind, as he was in for imaging relating to faecal incontinence. It's a close thing, but I'm going to say that cash is more disgusting.
