Terrible experience Portalia

My son found 2 hairs on pizza. Cheese was attached to hair. Reported it to owner. They replaced pizza. My 11yr old took first hair and disguared it below table. When he found a second he informed us. We asked him to retrieve hair with cheese attached to it below table. He did so. We returned to restaurant as they do serve good food and ambiance was good. Owner (Sam) called me aside and accussed my son of planting a hair on pizza. We asked our son to retrieve second hair and addressed with management. Sam told me my family is never ever welcome. Embarrassed my family and left children unsettled. Unacceptable. Was also very aggressive in his tone and threatened police. Is this how we treat patrons???
