"Hotel Manager, hates people. Has a charming wife and lovely chambermaid at the hotel. Waiter is an incompetent fool who barely speaks english. You get annoyed on a regular basis because of him. Obviously a male waiter otherwise you wouldn't have so many frown lines. You despise foreign people, losing your temper even more when they are at your hotel, named Fawlty Towers. Your hotel is in Devon, most likely Torquay. You are constantly annoyed or angry about something. hell to live with, don't know how your wife does it. Am I right?" Sherlock made his deduction.
"Spot on." said Sybil Fawlty, Basil's wife.
"How incredibly rude!" Basil protested
"See, I was right, always annoyed about something. and Its not rude, It's my job, I'm a consulting detective. Which basically means that when the police are out of their depth - which is always - they consult me."
