Can I just give you some advice ..please.

Support that business with regular purchases and also encourage your friends to support it to, because if you do not do that... the owner will decide to remove that payment option.

We had a few businesses in my area that also decided to do that, but he got almost zero transactions and he also struggled with BitPay and then when I visited the shop again... he stopped accepting bitcoin as a payment option.

Also ask him to give a small discount to people that pay with bitcoins, because that will be the incentive for people to rather pay with Bitcoin than Fiat currencies.
