What are some disadvantages of a mug?

Some disadvantages of a mug include its bulkiness, which can make it less portable compared to travel cups or bottles. Mugs are typically made of ceramic or glass, making them prone to breakage if dropped. Additionally, their larger size may lead to beverages cooling down more quickly, potentially affecting the enjoyment of hot drinks. Finally, they can be less versatile for on-the-go use, as many mugs lack spill-proof features.
