To me cash is just a nause. I have hardly any need for actual cash in my life save a few quid in my pocket to buy a pint or a coffee once in a while and even then you can put it on a card most of the time.
For me cash, or a cheque for that matter means a 15mile drive each way to a bank to pay it in and only when they are open as the nearest one dosn't have a deposit facility. And I'm at work when they are open.
Irrespective of the safety issues I would rather the buyer had the faff and I got the money in cold hard electonic nothingness!
