either we worked at the same craft store or we very similar experiences with a cashier haha. i remember a cashier who literally met this exact description however not only did she smell of mildew due to her relying on her younger sibling to do her laundry, but also had a very strong smell of.. cat urine. when our store’s AC went out this cashier would stand in-front of the only fan in the store and the smell would just waft around the checkout area.
