In a daze of futures past

Julie's job at the hospital is to provide the patients with their evening meals and a spot of tea or coffee to wash it down. The thing is, the hospital is such a big place, they need to have some sort of system, otherwise they won't know if they're coming or going. To that end, they tend to have the same menu from one week to the next. However, Julie feels the need to write down what she will be offering on a particular day, so she doesn't get confused about whether it's chicken pasta bake day or corned beef hash day.
Or, as Julie put it...

... I'm going now. I've got a headache, for some reason.
