tiny prawns sticking to the shells

Price for prawn special went up, but quality went down. Was informed that the head office changed the type of prawns laat week. Two managers confirmed that prawns were smaller now and clinging to the shells. Main manager Ruan checked the boxes and informed me that there were only a few bigger ones in a box and rest were all small. He took pictures to send to head office. No compensation, eg free cappuccino, was offered. Had to pay the full bill. Shame on Ocean Basket which used to be one of my favourite restaurants.
