Quite agree, Mikey. I like some of the stuff Lidl does (especially their Cava, which I believe you are somewhat partial to). But the business that you describe with the tills drives me and Mrs NJ crackers. Worst of all, you’ll be queueing for ten minutes, then they announce another till is opening and people who have just finished their shop go straight to that till and get served immediately! Aaaaargh!
I know their staff “multi task” but the frequency with which tills open and close seems a very strange way to run a shop!
