Coffee
Coffee is available within walking distance of most humans in developed nations, and increasingly in developing ones. Instant varieties have penetrated markets where fresh water remains inconsistent. The beverage costs between pennies and pounds depending on one's tolerance for pretension. From petrol stations to Michelin-starred establishments, coffee adapts to every economic stratum. It requires no appointment, no visa, and no emotional preparation. It simply exists, waiting, in approximately 38,000 Starbucks locations alone.
Panda
Viewing a panda requires either significant travel or extraordinary fortune in zoo proximity. Approximately 600 pandas exist in captivity globally, distributed across fewer than 50 locations outside China. Wait times for panda exhibits can exceed two hours. The animals spend 55% of their time sleeping and may not deign to be visible during one's allocated viewing window. The panda is not inaccessible because it is rare; it is inaccessible because it simply cannot be bothered to participate in its own celebrity.
VERDICT
Coffee's universal availability versus the panda's cultivated scarcity creates no contest. One can be acquired in minutes; the other requires planning, travel, and the acceptance that the main attraction may be facing the wrong direction.
