I once had a stand off in a "coffee shop", my wife drinks coffee, I drink tea. She sent me to order the drinks.
Moi - "Could I have a tea and a white coffee"
Staff - "What type of coffee"
Moi - "I told you white"
Staff - "Yes but what type of white coffee"
Moi - "The type that comes in a cup"
Staff - "But we have many different types of coffee"
Moi - "It says on the sign, coffee shop, not the many different types of coffee shop"
Staff - "But we do many different coffees"
Moi - "Just give me a coffee, with milk, in a cup, the coffee it says above the door"
Staff - "Do you mean a nescafe"
Moi - "I don't care about the brand just give me a coffee"
Wife - (appears from nowhere), "You go and sit down, I will sort it out"
Wife - "I want the sort of coffee you would make at home with a kettle and a jar of coffee in the cupboard and some milk in the fridge"
Staff - "Ok"
