There are a lot of odd things that have resulted from the US government shutdown. For instance, the network of shuttle buses that government employees routinely use to get from one location to another are non-essential. This means that those folks still at work who routinely use public transport have to find a different way to get between work locations than they are used to. This may include taking their own vehicles to work (extra costs for parking and driving) or using a taxi service (more extra costs). This is additional pain for those not getting paid at this time but are obliged to work.
