In retail, the store itself is part of the product. Smudged glass at the entry, scuffed floors along the main aisle or a cluttered fitting room tell a shopper the brand doesn't care, and they walk on to the next window.
Cleaning in retail has to work around trade, deliveries and stocktakes. Stores that rely on staff to clean between serving customers usually end up with the sales floor done and everything else ignored: the stockroom, the staff toilet, the dust on top of the fixtures.
Area and store managers need someone who keeps every location to the same standard without needing reminders.
