"A major quick-service chain accidentally promoted National Sandwich Day for November 3 without noticing the date fell on a Sunday, a day when its locations are traditionally closed. The company followed up with an apologetic email explaining the oversight, reminding customers that it operates Monday–Saturday, and expressing hope to see patrons soon. The marketing misstep drew attention on social media and prompted suggestions it may need another promotional push to smooth things over, though the chain remains commercially successful." - Jaya Saxena
