I smile at them pleasantly and offer to help them with whatever their wants/needs are. If they require a special order I get it fixed right away. Also I always ask how I can make their experience a perfect one. If they require a manager also I hurry right away to seek one. I always make sure to stock everything so what they seek will be on the shelves. I even give them tours of the store so they have an idea what Petco has to offer!
