"I've sold, like, 100 this morning," a staff member tells the BBC. But it's not baked goods driving queues out of the door - customers are here to buy eclipse glasses. They are among those hoping to catch a safe glimpse of Wednesday's solar eclipse - the UK's most significant since 1999 - but struggling to get their hands on the right gear. Experts have urged eclipse enthusiasts not to look directly at the Sun - with even brief exposure causing lasting damage - and to seek out specialist glasses instead. Meanwhile, eclipse glasses have been turning up for sale in unexpected places as retailers try to capitalise on the demand.
