Have some fun with him instead of being pissed.
Everytime he yells shut up - Clap loudly and yell "HURRY UP AND BUY" after about the 4th - 5th yelling this back break out to the closest pay phone and send a cab to his house - tell the cab company that your "friend" has had too much to drink and needs a ride ... Even if he says no.
10 minutes after the cab leaves (with or without him) .... hit the same payphone and send chinese take out to his place and a pizza from somewhere else ...
Buy the time the Chinese take out guy is done working out on him for a false order and ensuing argument - The pizza guy should be there to work out on him next until the neighbor is nearly insane not knowing where the food is coming from or the cabs.....
Post pizza guy leaving break out for Trip 3 to the phone and ONLY if you have 2 cab companies in your area - Fire off another cab to him that he's hammered and needs to get to the local airport.
At this point its cost you about $1.00 - $2.00 or so in quarters and he'll be inside his house hiding in a closet in silence not knowing who is coming next to rattle HIS cage.
