"Passing through the airport, the writer had time to browse the duty-free aisles thanks to having travel documents and a mapped route on their phone, and stumbled upon an airport‑exclusive liter of Ardbeg Smoketrails Napa Valley Edition priced at 619 DKK. After an initial panic at thinking the price was in dollars, they used an iPhone calculator conversion feature (which pulls live rates via Yahoo Finance) to confirm the cost was about $95.40 — making the 33.814023‑fluid‑ounce bottle feel like an absolute steal. The same conversion tool also proved handy for quickly checking suitcase weight in kilograms, converting milliliters and other metric units, and handling recipe and temperature conversions, underscoring how the duty‑free shopping experience here can be relaxing and rewarding when paired with useful mobile tools." - Kat Kinsman
