If I were you, I will go to YouTube and type "Video of someone using bitcoin ATM". This will return many results and you will understand much more details about it.
You are correct; there are plenty of videos online that could have pointed the OP to the right part, but I personally don't trust everything I see on the internet nowadays, so there is still nothing wrong with what the OP did, as he or she can gather whatever data they are looking for here, as I consider here as the best place to source data.
Here is far from being the best place to source data or information. To me, the advantage of using here is that you will have your data or information in the form of discussion, whereby if anyone gives you a wrong data, another will immediately give a correct one. And you can return to ask more questions.
There's no bitcoin ATM in my country, so I haven't used it and there's no going to be one. This is because bitcoin ATM is no longer the trend. Exchanges p2p have made the need for ATMs less.
From your post
history you are from the Nigeria local board, which means you are a Nigerian, and
according to CoinATMRader, there are actually two Bitcoin ATMs which are located in Lagos State, Nigeria. Not sure if they're still active, but they were still there according to data online. But how many people are actually going to use it considering the security implications? Just as the use of normal bank ATM machines is reducing, everyone is going mobile.
Yes, I am a Nigerian but I haven't heard of a bitcoin ATM in Nigeria. If you said it exists in Lagos, it could be in the Ireland and I doubt it is still in existence now. Bitcoin is partially not legal in Nigeria
