"This is not a free supermarket" - Reconsidering Queuing at Food-sharing Events.

This paper addresses the sociotechnical challenges of organising queuing at large scale, face-to-face, food-sharing events. The authors have partnered with a grassroots food-sharing community, FoodSharing Copenhagen (FS-CPH), to reconsider queuing practices at food-sharing events. The results present three “queuing canvases” that illustrate how FS-CPH members envision digitally mediated queuing at food-sharing events. The paper outlines three themes that emerge from this design work: communicating activism through queuing, encountering others through queuing, and transparency in queuing mechanisms. We discuss how the envisioned ideas illustrate novel perspectives on queuing in volunteer-driven settings, while sometimes falling back on accepted norms and common expectations of how queuing should work. To address this, we present a set of sensitivities, for designers and activists alike, to design for queuing in settings where non-monetary sharing is central.
