Strange thing. I sometimes use this last resort chain for one or two items only and would not dream of using it for anything else. Asking around people I know it turns out they all do likewise, just one or two items only. When I ask why it is for a variety of reasons, two of which I will list here. Fresh produce they mainly leave alone because of the lack of "use by" and "best before" dates. Although some items do have an obscure coding so staff know. Actually these can be found online. Next is untidiness. Next are the checkouts being ludicrously fast.
