Think of it as a public metro bus, only you're on it forever!!! You get what you pay for... $40 can barely buy lunch, so I really shouldn't be surprised that a commute to LA at that price would be less than pleasant.
I guess I'd be less disappointed if it were just called CRAPPYBUS, and there was an honest disclosure that WIFI doesn't work, and your bus may have no power outlets... And those amenities aren't guaranteed... then I'd leave at least 3 stars for honesty.
