This reminds me of a woman who complained to the french matrie d' at a restaurant I used to work in (true story)...
(As told by a waiter who observed the entire scene)
Woman: (Extremely irrate) The water in the bathroom sink is too hot...I burned my hands!!!
Matrie d': (Extremely French) Madame, most people choose to mix the hot with the cold when washing their hands...(walks away)
Classic!
