Print QR code up of your store's address, with text version below. Put preev.com in one browser tab, blockchain.info/address/youraddresshere in the other. Customer comes to checkout, says "I'm ready to checkout, what's the Bitcoin price?" You put the fiat value in preev.com, it live-converts it to BTC. You tell the customer. Customer scans QR or types address in their mobile wallet, fills the amount, sends it. You hear a beep from blockchain.info - that is the unconfirmed transaction. Since double-spends are unlikely with mobile clients, you print a receipt using the txid, hand it to customer, done.
