Thanks for letting us know about this incident. I am sorry to hear about your disappointing experience. Your preference for working at a computer workstation rather than with a laptop is perfectly legitimate. Workstations located near service areas can be problematic if you are hoping for consistent quiet, however, since occasional noise disturbances are unavoidable there. Though the discussion you witnessed may well have been social, we also assist library patrons there, and it is easy to slip into conversational tones in these instances.
The computer lab LB 203 is a silent blue zone that offers workstations and you would have a good chance of working in silence there for the next few weeks, though this will no longer be a solution in September and October when the room will be reserved for library workshops.
There is currently no perfect permanent solution for students who wish to work in silence at computer workstations, though it is something we are looking at. Your comment will be on the agenda at our next noise and staff meetings. Thanks again for writing to us.
