Poorest service at Mams mall

On Friday the 25th experience the poorest service ever in a food outlet place an order @ 18:30 got to the shop at 19:05 order was not ready not even loaded on their system had to wait for 2 hours for an order place on call and collect the shift manager was so clueless as if his new more 8 people demanded money back due to that service I wonder if Petros provide such services everywhere or on black or local outlet
