Thanks - I'll keep doing the Berko market and now I'm looking for a busier one to add to the turnover.
I've worked in commercial kitchens a long time ago as student jobs. McDonalds first - fun to begin with and teaches you to be systematic - then various one for Compass Services including Hamleys and the Natural History Museum.
Natural History Museum was the the best one - the cold store was in tunnels underneath the museum where loads of the collections and items not on display were stored. Used to wheel trolleys full of ingredients past giraffes and dinosaurs wrapped in plastic sheeting. Always brought a smile to my face.
