Oliver works as a freelance programmer on a very demanding project. After working late, he has difficulty getting up early. His ambitious interim manager was angry about his constant lateness, therefore threatened to fire him, if he comes late again. So on a Saturday, Oliver went to see his doctor who prescribed him a strong sleeping pill and told him to take them just before going to bed.

On Sunday evening, Oliver did what the doctor said, and slept very deeply. When he woke up, he felt very refreshed and his alarm clock showed 5 am. So he had time for a long great breakfast and drove luckily to work where he had plenty of time for the start. He even arrived before his ambitious manager, telling him how well the sleeping pill worked. His manager responded: "That is all great, but it seemed to have worked too well. Today is Tuesday and you did not come to the office yesterday!”
