I don't usually venture into Gulliver's panic news section, but, as a shelf stacker at Morrisons I can report full shelves here, no shortages of loo/kitchen rolls, plenty of fresh fruit and veg from all over the world. Our department (fresh food, pre-packed) is bulging at the seams; in fact we're getting rollickings for our waste and markdowns being high - basically due to the large volumes we are getting daily. (NB we are giving plenty to our local charities, etc).
Do wish the OP would stop stirring that big wooden spoon.
