McDonald’s Retail crossing Jhb

Manager at McDonald’s Retail crossing ruined my day and appetite! Our food was served to us cold because she was very uncooperative! Her name is Mpho I’ve never been so disrespected ever in my life! Customer is king what ever happened to that ? I was very polite to her but she was very rude and didn’t care for my concerns! The rating should be 0 not even 1!
