After posting a lot of adverts and promos about free Uber rides in Minneapolis, Uber suffered a direct hit when their app failed multiple users.
The road to hell is filled with good intentions, and this is the case for Uber on St. Patrick's Day in Minneapolis, when Uber suggested that it would help reduce road incidents from drunk driving, by offering free rides to customers when entering the promo code "INDYSTPATS." The promo was for one ride between 11am Saturday morning and 3am Sunday morning, and for rides that don't exceed $15.
Many customers received this message "promotion redemption limit exceeded." Which did not add to Uber's still dented image.
