Well to be fair, almost nobody who ever uses Bitcoin to pay for something will ever involve the merchant accepting Bitcoin. In all the times I have seen Bitcoin accepted on a website, they use a 3rd party payment processor (like Bitpay is the most famous).
This means you send BTC to the processor, the merchant actually never gets any BTC but a fiat payment.
This is the way it works.
Like how it works in my country it was able to pay any merchants partnered with them thru shopping, travelling and even hotel booking via traveloka. Even in 2018 it was already operating and was able to use it. They will use 3rd party app which as a bitcoin wallet that's when you will choose to pay via fiat or BTC but still in the end they will convert to amount they ask to pay. Anyway it still much ok than not having any option of using it, many service might be soon available with the use of cryptocurrencies.
its a luck for you that there are companies in your country that having an option to use Bitcoin as payment method.
i am eager to find here in my country but the bad thing is there are still no option of having such.
though there are some merchant that accepting as payment from online purchasing.
For my own decision if there are same offering here in my country?i will surely grab using my bitcoin or other altcoins because for me?
it is a privilege to help Circulate bitcoin and other altcoin as well.
