Sherlock Holmes and his side kick Watson check into a budget hotel to conduct surveillance on the brothel opposite.
After a few hours of futile waiting next to the drawn curtains, Watson was feeling very thirsty indeed. He opened the mini-bar fridge and look through all the drinks, but they were depressingly expensive. He finally grew so frustrated, that he made a move to drink from the tap in the bathroom.
Sherlock stopped him by tossing him a bottle of Evian.
"What is this my dear Holmes? How are we going to afford this?"
Sherlock looked at the good Doctor gravely. "Complimentary, my dear Watson!"
