They are complaining because they end up spending all that extra money from those “high paying” MMP contracts on hotels and food while they wait for their next job. Or maybe it’s because they finally realize that the A books have all the highest paying jobs locked up. And all the scraps actually don’t pay as much and are equal to or even lower than AMO nowadays. Or they could be mad because AMO has had an online job board forever and can pick up the phone to claim the job rather than race people to the hall.
