I know I lost quite a few sats (far more than I keep in my Alby wallet) trying to set up and use my lightning node, pay fees for channels, additional liquidity, etc. Then if I factor in the sats I lost on dumb user error as well - I could zap for the rest of the year on that.

I no longer have any open lightning channels on my node, by design.

And I'm relatively technical, had no problem at all building a raspi or working in a linux CLI. I can't imagine what it would be like for your barber.
