A recent study by Preply has ranked Miami as the rudest city in the U.S., with Tampa coming in third and Charlotte at tenth. Miami residents themselves acknowledge their rudeness, scoring 9.88 on a scale of 0 to 10 for behaviors such as lack of self-awareness and rudeness towards service staff. Tampa's ranking may reflect the state's recent population influx, which some believe has influenced social interactions. Meanwhile, Charlotte residents contest their ranking, arguing that southern hospitality is a hallmark of their culture. The study highlights subjective interpretations of rudeness, with behaviors like talking on speakerphone in public spaces being universally frowned upon. The survey also pointed out that the most polite cities are Omaha, Minneapolis, and San Diego.
