With no confirmations a double spend is easy (would require a custom Bitcoin client designed for the purpose). Is it likely? No. So, if I ran a coffee shop, I'd hand over the goods without confirmation. If I were selling a house or a car, I'd wait for a whole lot of confirmations. Digital goods probably don't need to wait, either, particularly for returning customers. So, yeah, I agree...I just want to be clear about why the risk is low: Because most people aren't going to cheat you out of a cup of coffee.
