Half Agreeing To Half And Half

(I am joining my family for dinner when I overhear this exchange between my mother and our waiter:)

Mom: “Can I have a cappuccino?”

Waiter: “I am sorry, We do not have any.”

Mom: “Do you have any green tea?”

Waiter: “Yes, ma’am.”

Mom: “Can I have that with vanilla?”

Waiter: “We do not have any vanilla.”

Mom: “Nothing vanilla.”

Waiter: “Vanilla vodka.”

Mom: “Peppermint? Gingerbread?”

Waiter: “We do not have any flavorings.”

Mom: “Any [Flavored Creamers]?”

Waiter: “We have half and half.”

Mom: “See, I did not want half and half.”

(My father breaks his silence and speaks up and says to the waiter.)

Dad: “Just say yes to whatever she says and bring her half and half.”

Mom: “That works for me.”
