I’ll take you word for it as I’ve never placed a bet with a bookie.
I bet with friends and might have broke even but mostly I just got broke.
Same with other gambling which is why I don’t do it.
You can see my record here and at yahoo and see why!🤣😂
Even betting with friends, you should be aware of the point spread. If you are taking the underdog you are already at a disadvantage.
