Sanderson & Grainger

Sanderson & Grainger was a department store in Colchester, at which the Eleventh Doctor once briefly worked in 2011.

The shop housed a Petrichor advertisement, with Amy Pond as its model. It was located directly over a small Cyberman base and was infested by a "silver rat", in reality a cybermat. The Cybermen there were culling the store's staff, whose body parts were then cyber-converted.

Other workers there included Shona, Kelly, George and Val. (TV: Closing Time)
