Money Laundering

I sell Greetings Cards of local views (my photographs) around Hebden Bridge and district.  One of my customers is a lady on Hebden Bridge Market.
Being a market trader she deals in cash - which I am normally very happy to accept :-)  When I delivered an order to her today she gave me the cash, in a plastic bag.  She said she had disinfected it all but maybe I would like to do so again - so I did.
Here it is drying out - amazing how life has changed with Covid - (but I still like cash)  :-)  :-)
