Leo begins to speak up "Billy, he..." before almost immediately getting interrupted by Billy, a yell you've only heard him use a handful of times letting people know he is in no-fucking-around mode "Leo, NOW!"
Leo stumbles back a bit before reluctantly crawling into the passenger side of the truck. Billy turns back to the store owner, a much quieter but still serious tone "I apologize, Mr. Miyamoto. What happened here?"
The old man's face calms a bit at the control and respect Billy showed "I've been dealing with the family for years now with no problem but I've never met such an insolent little brat. I don't want any trouble with you guys but I don't know what else to do if I'm treated the way he treated me." Much noticeable than before, his left eye has become swollen and red.
Billy grabs the man's face and looks at the swelling for a bit "I'm deeply sorry, Mr. Miyamoto, if I had known he would of treated you this way I would of sent one of my personal boys in to get you, not him. Rest assured, you can continue to deal with us with no problems; I'll tell the boss he is unfit for this delivery job and you won't see him in your store again, I promise you that, Mr. Miyamoto. I'll give you two boxes, one of each, on the house in hopes you don't think of The Family wrongly because one boy is on a power trip."
The man pats Billy on the hands "Now there's the kindness I'm used to." Billy gives the man a nod then turns to the three of you "Let's get the boxes in the store. Whites lids have cigarettes. Blue lids have wine, so be careful with those." The four of you begin bringing the boxes from the truck and into the store, Miyamoto gives Billy a stack of cash after a couple deliveries, and Billy yells at Leo to stay in the truck after he catches him starting to climb out of it. After you finish bring the last of the boxes in Miyamoto hands each of you 5 dollars, Billy hands back the money he was given "Thank you but after today's fiasco, I cannot accept it in good faith. Pay me when our drop offs go through without any problems."
