How to help a business to accept Bitcoin

Hi, I would like to know tips on what to say to a business owner so he or she considers accepting Bitcoin. I ask this because my mind is so bitcoinized(?) That I may miss what normal people thinks about it. I can think the part about not huge bank comissions, instant, secured by all the network, easy to use. Obviously I would have to explaind more wildly these points, but are there any more that can be seen like a good way to convince them? I live in Europe, Spain so almost anywhere we have euro accepted by card.

Thank you very much in advance!
