While we're in the midst of looking for people to fill out our rather thin looking rota the owner has brought in a friend to help out.
He's never served before, or worked in a restaurant, he's an electrical engineer, but he's about my age, good looking, and he seems to have gotten the hang of it remarkably quickly for someone with no experience.
We're explaining what to do and giving him small details regarding service and seating people and he makes the point:
"You'd seat 2 people at a table for two, common sense"...
I glance meaningfully at the hostess. She's never figured this out, she seats people, on nights we're fully booked, without confirming their reservation and wherever she first happens to trip in the dining room, the size of the table is of no consequence. She understands and looks sheepishly at the floor.
Common sense, yes, but how rare it is...
