" [...] I started giving them the postcode for the Asda store, [...]"
I always use the post code of the Royal Mail sorting office in situation where it is not necessary for them to know the information but the form won't complete without it. It is near enough so that correlation with any other geographical references would be plausible. Some of them are getting canny and have decided that the memorable old post code of a major bank is not plausible since they moved locations.
