At Monk's, a waitress banters playfully with George. Elaine returns from England with a boyfriend named Simon, giving him plane tickets that let him stay as long as he wants. Jerry has an unwanted run-in with comedian Kenny Bania, who boasts about bulking up too much to fit his Armani suit, and promises the suit to Jerry without him asking, impressing everyone but Jerry. George is so taken by the waitress that Jerry strong-arms him to go back into Monk's to ask her out. Kramer's kidney stone episode inspires him to give up his refrigerator so that he can only eat food fresh.
Bania brings Jerry his suit with false charity, obliging Jerry to treat him to dinner in return. Simon lands, and immediately takes exception to Elaine's mannerisms. George goes on a walk in Central Park with Kelly, the waitress; he puts a positive spin on the horse manure underfoot, and she immediately mentions that she has a boyfriend. Jerry clues George in that this might have been pretext for being turned off.
Bania picks the restaurant and time for the meal Jerry owes him, but then decides that ordering only soup will keep Jerry on the hook for the meal another time. Jerry protests, to no avail. Later, Elaine tries to settle which soups count as a meal, missing the point that Jerry must keep paying the price of Bania's company. Simon sponges off Elaine and Jerry, and goes out boozing and womanizing.
Back at Monk's, Kelly now treats George gruffly. Bania barges into Jerry's booth, and orders soup and a sandwich; between the two soups, Jerry puts his foot down and declares his debt paid, to Bania's displeasure. Kramer's girlfriend Hildy, a waitress at nearby diner Reggie's, confirms for George that Kelly has no boyfriend.
Elaine looks forward to Simon running out of money and leaving, and Jerry hands off the unwanted Armani to Simon. Kramer, having no food to sate Hildy's hunger and low blood sugar, desperately scavenges Jerry's kitchen at her command. George becomes too self-conscious to patronize Monk's, forcing Jerry and Elaine to eat at Reggie's with him. To their dismay, Reggie's will not make egg white omelets or big salads for them as Monk's does.
George schemes to get Kelly fired, just as Kramer has gotten Hildy fired by calling Reggie's too often. However, George's calls draw Kelly's boss's wrath on himself instead, and he gets banned even as Kelly finishes with her waitress side hustle.
Bania arrives at Monk's to demand his suit back, followed by Simon; the suit has gotten Simon a foot in the door for a job, which could extend his stay indefinitely. Elaine sends Bania after Simon, causing a scuffle that destroys the suit. George dines at Reggie's alone, in silence.
