Berkowitz is a frequent customer at Uncle Monty’s Sandwich Emporium. When he goes to the grand reopening he orders 10 corned beef reubens, 2 pastramis, and an egg-salad wrap. When his Groupon discount brings the price down to only $9, he doubles his order. When Jimmy Gibbler announces that due to unforeseen circumstances they no longer have supplies to give them the sandwiches they've come to expect and deserve, Berkowitz starts sharing his sandwiches with other customers.
