How would it be saving money? If anything libraries are losing money due to the suspension of fines, charges for certain items etc.. The libraries are staffed, so again no savings there. My understanding is that staff are currently working hard to make sure the library is safe for both staff and service users, remember a lot of the people who use the library regularly are vulnerable, maybe having less understanding of social distancing, increased hygiene etc.. Shops, PO etc. are not places that people go and spend the whole day to use various facilities. Be patient and support your libraries by using the current click and collect service which is actually functioning very well.
