Milkshake

Milkshakes were an Earth beverage.

Ace, while working as a waitress in a café on Iceworld, served strawberry milkshakes to the Seventh Doctor and Melanie Bush. When one customer complained about the quality of her milkshake, Ace tipped it over the customer's head. When her boss, Anderson, fired her for this, she tipped a milkshake over his head too.

Eugene Jones favoured banana milkshakes. He ordered one when he visited Happy Cook. Gary forced him to drink the milkshake whilst Josh performed the Heimlich Maneuver upon him, in an attempt to recover a Dogon Sixth Eye he had swallowed. (TW: Random Shoes)

The Tenth Doctor bet he could get Martha Jones the greatest chocolate milkshake she ever had. They travelled to such places as Costa del Centauri VI and 1950s Wisconsin, until they finally went to Korova Moo. (IDW: Agent Provocateur)
