A good point is they don't use a 3rd party for the transactions, they created the app with BTCPay. Usually, the merchants like to use something centralized like Coinbase or BitPay. If you wanna see a video using it

I for one wouldn't be overly enthusiastic about this use case
Most certainly, after an initial rage and rush with trying out real-life payments for things like a glass of beer (or a cup of tea if beer is not your thing), people will get back to their deep-rooted practice of keeping bitcoins and spending fiat instead. In other words, LN is not going to help Bitcoin adoption (at least not in a considerable degree). Changing spending habits and consumer preferences would help but that is beyond our control or influence as it basically requires rewiring human brains en masse (and we are not there yet)
Yes true but what about if I can buy my coffee cheaper?
When I pay with my card and a POS terminal, Visa charges a fee to the merchants. I don't remember the % but it's something not negligible for a merchant.
Let's say the fee is 2%. Since the merchant saves 2% he can say, ok I lower my price by 1% for folks willing to pay with BTC.
Yes lowering 1% isn't a lot but people will be happy to use BTC to pay cheaper. When there is money people listen to, a dollar is a dollar and nobody refuses to save money
