I find that the volunteers are hung up about money and funding and are always going on about it to members of the public. I've just come in here and there is no desk space because ive come in with my laptop. Then three of the volunteers gang up on me to remind me they are volunteering and not Lewisham council and they have money issues! Why are you telling me this? I only walked into a library supposedly open to the members of the public!
