Dinner at George's (S01E05)

Winston informs Fred that Evelyn's favorite dining spot is an upscale restaurant, prompting Fred to take her there. Believing that Fred might struggle with the bill, Evelyn discreetly steps away to "freshen up" so she can cover the extra costs beyond the $34 he brought. Fred realizes what's happening and, feeling insulted, leaves her at the restaurant. Back home, he finds some silver dollars and decides to give them to Evelyn to reimburse her for the dinner. When she cashes them, she discovers they are rare and valued at $1,500. She returns the money to Fred, and from that, he repays her the $100 for the meal.
