Identifying a tourist often comes down to observing behaviors that suggest a lack of familiarity with the local environment. One of the most obvious signs is "navigation-induced hesitation"—stopping in the middle of a busy sidewalk to look at a map, a phone, or street signs, which disrupts the natural flow of local foot traffic. Attire is another major giveaway; tourists often wear "functional" gear that locals rarely use in their daily lives, such as heavy-duty walking shoes, sun hats, or zip-off cargo pants in a metropolitan setting. Carrying a physical camera around the neck or wearing a lanyard with an ID or room key is also a classic sign. Furthermore, tourists tend to look up and around with a sense of wonder or confusion, whereas locals are usually focused on their destination and move with a specific "rhythm" and speed. Language and volume also play a role; tourists often speak louder than necessary and use "tourist-book" phrases or struggle with local transit etiquette, such as standing on the wrong side of an escalator. Lastly, frequenting highly-rated "tripadvisor" spots during peak hours instead of local "hidden gems" is a telltale sign of someone visiting from out of town.
