"The CCD regrets that inappropriate behavior by six individuals in a 20-second incident that disrupted a relaxing after-work event at one of 90 participating venues last evening has cast a shadow on a highly successful promotional event that hundreds of thousands of guests have enjoyed for more than 11 years," the Center City District said. "The CCD is responsible for marketing the SIPS promotion and continues to urge guests to behave in a responsible manner and   bars and restaurants to monitor the safety of their guests."
