@mcc seriously, if you're well off please leave the public library spaces & facilities for people who really need it.
At least fairly obvious in #nz It is likely that is the only heated shelter vulnerable get through the day and only place they have access to internet & even access to computing devices.
So rather than free loading & be smug it was paid by your taxes and "entitled" to use it, find somewhere else to spend time and just go to the library when you really need to use it.
Fill the library with active users and show that you need to expand it.
If the people in your city have nowhere else to go to exist in a warm space, that’s a serious gap in public services that should also be attended to. Your library shouldn’t be stuck operating as a homeless shelter because the government didn’t want to pay for homeless shelters, just as teachers shouldn’t be stuck working as therapists because the government didn’t want to pay for therapists.
