I’d likely let him save a little face
by not putting him on the spot, but somewhere in the world of your friendship it’s likely he has or will become aware of the fact you make money from what the casino makes and that translates into what people loose— so without pointing the finger straight at him, you could even causually talk about earning money from what people play & loose, (course if you don’t ever want him knowing this than I suppose that options out). But if he is aware of how this business works than you could still put it out there and let him put together the dots to realize you likely know what he’s really playing and loosing, Which would allow him to gracefully stop BS’ing you. Just MHO.
Of course if he’s a really good friend he may want some back. hehehe
If he’s killing the family budget and he’s your friend tell him what the F you know. That’s my other HO and two bits.
Gambling always has big fish stories. When ya catch em and when they get away. Seeing his stats is a very candid picture of that fish.
