Rude Attitude and Convenience

Customer service plays a huge role in the business and its sad to see employees have a rude attitude towards customers especially on drive through. I am disappointed this morning I had to wait for a breakie wrap while other customers were served in time through the drive through. Surprisingly I qued behind a client who was having card issues I feel through inconvenience the client could have stepped on the side or went inside to be helped. When it was my time to pay and I ask what was the situation I am told network issues the card machine has a problem but when I swiped I was able to pay then I was made to wait for long. What is the point of a drive through? KFC Thabong needs to check out there staff with rude attitudes.
