unhappy

Would like to complain about service i received earlier today at rivonia MacDonald .we firstly asked the cashier if we can consume bought from another shop n she said no it's not allowed which we respected and ordered from them .while eating the other lady then sent security guard to check on us n we asked him why he's looking at us like that boo on his response was so rude n gave us attitude ...opposite us was 2 guys eating simba chips n alcohol but no one went to check them .we felt belittled n our money not valued .therefore the security guard doesnt have respect for customers.Please a dress this
