Why do they skip the letters I and o in auditorium seats?

The letters "I" and "O" are often skipped in auditorium seat numbering to avoid confusion with the numbers "1" and "0." This helps ensure that patrons can easily identify their seats without misinterpretation. Additionally, it minimizes the chances of mix-ups during ticketing and seating arrangements. This practice is common in theaters, stadiums, and other venues where clear navigation is essential.
