"Good Samaritan corner" in the lab

Good Samaritan corner is needed in research lab. In my lab, common reagents/solutions were prepared by a single person and shared by many people. That took a toll on that person (especially when someone later complained about lack of solutions that affected experiments) and since then, there was no longer common reagents/solutions and everyone was supposed to prepare his/her own solutions.

I'm planning to assign a corner (or other places) in the lab "Good Samaritan corner" where we can volunteer to prepare solution without any expectation of its availability. If the solution is unavailable, no one should should, "solution A is empty!". The corner will be "you reap what you sow", in which the availability of common solutions is a shared volunteerism.
