Here’s my proof. Via agency I’ve worked as a driver at these RDCs-
Tesco- Magor, Avonmouth, Harlow (closed now I imagine), Welham Green, West Thurrock
Sainsbury’s- Waltham Point, Elstree, Hatfield,
Iceland- Enfield & Swindon
Gist/M&S- Hemel Hempstead
Arla- Oakthorpe & Hatfield Peverel
McDonalads- Hemel Hempstead & Heywood
That I can remember And delivered to a great many more including all the major retailers here and many abroad and you know one thing common to them all outside Lidl & Aldi? Never even been in 90% of the warehouses let alone to work, normally just having to walk through them. If CF worked some time in past 20 years he’d know drivers going into warehouses for any reason let alone to work in vast majority of places is a big no no
