A waiter working in a café went on a break for 15 minutes. He was feeling sick with the flu. In the break he went to the toilet, did not wash his hands, went outside and had a cigarette, still did not wash his hands and then went straight back to his waiting duties.
• His first duty was to deliver meals to a table.
• His second duty was to take an order from an elderly group of people at another table.
The next day customers from both tables called the restaurant to let the manager know that they had been vomiting and having severe stomach cramps.
