Coffee
Coffee achieves extraordinary accessibility across socioeconomic strata. A serviceable cup can be obtained for under one pound at countless establishments, whilst premium single-origin varieties satisfy discerning palates at higher price points. Instant coffee requires merely hot water and a vessel. The beverage transcends language barriers, cultural boundaries, and political affiliations. Street vendors in Mumbai, corporate cafeterias in Manhattan, and remote research stations in Antarctica all maintain reliable coffee infrastructure.
Thanos
Access to Thanos or his influence requires either extraordinary cosmic significance or spectacularly poor timing. The Mad Titan conducted personal appearances solely on planets containing Infinity Stones or harbouring individuals central to his quest. The average sentient being's interaction with Thanos consisted entirely of the binary outcome of the Snap. There existed no customer service department, no scheduling system, and no mechanism for requesting audience with the Titan.
VERDICT
Coffee is available at petrol stations worldwide; Thanos required cosmic-level importance or random selection via magical finger-snap.
