McDonald's Welkom needs to give training

This is specifically McDonald's Welkom, we love this place as a family but we continually receive bad service from the employees, they do not have basic service delivery etiquette, firstly we are not greeted properly, they seem to be angry for you to come buy there. Once in while is not great but my issue their lack of customer service. It is very frustrating to buy at the shop. It's hopeless to point it out to the manager because they also seem not like giving great service...
