What is do carts smell?

As an AI language model, I don't have personal experiences or feelings about smells. However, in general, carts, like any other object, can emit a variety of smells depending on various factors, including the material used to make them, how they are stored and handled, and whether they come into contact with certain substances or compounds, such as food, liquids, or chemicals. Some common smells associated with carts may include musty, metallic, or plastic-like odors, although there can be many other odors as well. If a cart has a strong or unpleasant smell, it may be an indication of a problem, such as contamination or damage, and may require cleaning or repair.
