No service at Steers N2 Durban

I have been at Steers at Inanda road at total truckport on the N2 towards the airport. Wanted a toasted king steer burger, because I am allergic to sesame seed. I wanted an extra egg on burger as well. I was told they cannot do that because they have to stick to the menu. They cannot provide egg because that is part of breakfast which end on 11h00 in the morning. I was not served at all. This is a ongoing problem at this store. It seems that there is only a certain group of people that they serve at this outlet. Very disappointed.
