Poor work force management

Yesterday I visited the pep at Johannesburg by albertina sisulu street. On arrival there was a q and only 2 tills were open. My issue is that the first till had someone who was activating a phone which usually takes longer than a normal transaction. The second till was operating normally but could not manage the numbers. Now my issue is that you cannot have only 2 till operators on the busiest pay weekend. Now when I finally get to the front I told them about their lack of staff available and as opposed to apologissing the are telling me that other staff members have knocked off already. As a customer how is that any of my problem. That is simply poor work force management. Bongilisiwe Langa please manage your people better. We cannot suffer as customer due to your enability to plan accordingly.
