Change your processes and give more variety of options

I don't understand why can't we swap a cold drink and pay the difference for the milkshake it's really sickening when you you don't have an option and the stuff is like it's fine you can take a meal with the cool drink and buy the milkshake separately..... More like wanting more quanyity to leave to get more money come one wake up guys it's a new South Africa give your customers options
