I had the same experience on a lunch appointment with some clients. I took them out for lunch and I paid with Bitcoin. They were very amazed and intrigued and we extended the

lunch to talk about Bitcoin. I helped them to setup a wallet and transferred some coins to them and to thank me, they paid with Bitcoin for some desert.

Out of the three of them, two still use their wallet regularly. { I still have their Bitcoin addresses, because I transferred coins to their wallets, so I can check up on them }
