Rude Salesperson

I was at Vodacom looking to get an S6 Edge contract. When I arrived at the store I printed out a ticket and waited in the queue. As I sat there I watched as people who had arrived after receiving help. At some point a staff member even came up to me and asked what ticket number I had. I saw her report it to the manager who looked over at me and then called the next person whose ticket number came up. After 40 minutes of waiting a salesperson eventually asked what I was waiting for and I told him. I asked for an explanation as to why I was left waiting for so long. He responded that it was because I had selected the wrong thing on the ticketing computer. I asked him how had I selected the incorrect option if I had selected \New Contracts
