Is it allowed to buy food for several days and use the food subsidy for several days? I.e. is it allowed to buy food on Monday, which will be consumed on Tuesday?
No, this is not allowed. The receipt date must correspond to the working day for which the food subsidy is claimed. In principle, however, it is irrelevant at what time the goods were purchased: e.g. purchase at the bakery before starting work and consumption during the lunch break. This means that the requirements are met.
