Nice!  I know how you feel. I just bought 3 donuts at a coffee shop in Portland Maine, using my Zues wallet, connected to my lightning node running on my Start9 server. That was my second LN purchase and it happened this past Saturday

The cashier had been working there a year and I was the first BTC customer. The owner had to come out from the back and we had to do a lot of math to get the USD to sats conversion. I also had to have my sister restart my start9 an hour earlier as my Zues app would not connect. So still some technical difficulties to smooth out. But yeah…. Hell Yeah!
