Standard stuff - and, as FF points out, they make their money on the booze.
I'm afraid Carluccio's drives me to distraction. I now refuse to go there because there is a good chance that if I do I may garotte one of the waiters. They are not the brightest.
A few years ago I worked on the second floor of a building. Carluccio's had the 4th floor. They used it for inducting waiters. There was a sign at ground level showing what was where, and signs at every floor. Every day of the week a confused specimen would wander in to our reception and say 'Carluccio's?' We would point them toward the fourth floor. They'd leave, completely bewildered.
The same with the restaurant. The waiters walk around very quickly, almost in a state of panic, with absolutely no idea where they are going. They stop. They ponder. They retrace their steps. Without a clue.
