I have also noticed several staff in M&S at ED station don't wear masks and have reported this on line to their Customer Service dept. I was advised that this would be taken up with the manager, but nothing has changed. In particular, the person who regularly serves on the bakery, wears her mask around her neck and the staff on the Help Desk are usually maskless. There also isn't a screen on the Help Desk, which I would have expected to be a standard fixture.
