Dollar Tree is a mixed shopping experience, praised for its cleanliness, organization, and friendly staff, particularly a polite cashier named Benjamin. Customers appreciate the great selection of items available most of the time, despite occasional empty shelves. However, some shoppers have reported rude behavior from certain cashiers, which detracts from their experience. There are complaints about the service being unfriendly, especially during busy times, and the need for more cashiers at checkout to reduce wait times. While some customers enjoy coming to the store for its variety and low prices, others have encountered negative interactions that left them feeling upset. Despite these issues, many still find value in shopping at Dollar Tree, thanks to its affordable prices and helpful staff, leading to a desire for improvement in customer service.
