Can I please just reiterate just how awesome our cashier, Justin, is? This review came about solely because of him.
Having bought: 3 fifths of liquor, a case of water, a 12-can pack of Coke Zero, a bag of pretzels, plastic cups, a razor and a travel-size container of conditioner, Justin was extremely helpful in terms of helping us figure out the logistics of carrying all of our crap back to Harrah's. Despite his coworker hassling him to hurry up (even though she genuinely didn't seem to be doing anything) and us insisting that we didn't need to rent a basket or a cart, he was still very courteous and friendly.
He even broke open the pack of Cokes and stacked the cans into a plastic bag for us so it would be easier for us to carry (rather than having to tote the box back, along with the case of water and everything else in our hands). AND he double- and triple-bagged just about everything to ensure that we wouldn't have to worry about the bags breaking halfway back to the hotel. Fantastic customer service.
