Kebabish bad customer service

Traveled from jhb to kzn for Holliday.. tried many restuarants and decided to give kebabish a try.. we were 9 in total. 6 kids.. 1 of the kids really wanted another fast food place food so we had stopped there and purchased for him a pizza that he really wanted and we proceeded to kebabish. Upon entering we were escorted to a table and then abruptly told that we not allowed to bring food from outside the restaurant into the place.. we told the owner /Manger that it was jus for the *** but he again abruptly said not allowed in a harsh tone.. we then walked out upon repeating this for the 3rd time and he did not want to listen to reason.
