(extrait d’une note de service)

By way of introduction, let me just make a few general comments on this subject. The problem of distributing bathroom tissue to workers presents inherent challenges for any
office management system due to the inherent unpredictability of usage-not every facility usage transaction necessitates the use of bathroom tissue, and when it is used, the amount needed (number of squares) may vary quite widely from person to person and, for a given person, from one transaction to the next. This does not even take into account the occasional use of bathroom tissue for unpredictable/creative purposes such as applying/removing cosmetics, beverage-spill management, etc. For this reason, rather than trying to package bathroom tissue in small one-transaction packets (as is done with premoistened towelettes, for example), which can be wasteful in some cases and limiting in other cases, it has been traditional to package this product in bulk distribution units whose size exceeds the maximum amount of squares that an individual could conceivably use in a single transaction (barring force majeure). This reduces to a minimum the number of transactions in which the distribution unit is depleted (the roll runs out) during the transaction, a situation that can lead to emotional stress for the affected employee.

However, it does present the manager with some challenges in that the distribution unit is rather bulky and must be repeatedly used by a number of different individuals if it is not to be wasted.
