The Short Bag

When Chrissie drops off his money he has to kick up to Paulie but is short by $2,000, why is that such a big deal? Why couldn’t Chrissie make it up on his own end, surely he had an extra 2k lying around he’s not living paycheck to paycheck. He knew he’d have to owe Paulie and pay it back anyway so why not avoid the headache of paying points on money he would have to owe and just pull the 2k from his own money
