Receipt guarantee

Posted from N73 through Flickr

Since the lack of extra time during last two weeks, I ended up having a take away pizza from Kotipizza. There's a good campaign against the grey economy on the box. -You get your money back, if you don't get a receipt..
 Take a note next time you eat in your local pizzeria what is their practice with the cash register. -Does it really print a receipt ;)
