Spar Carlswald - Why Cashier Change Over at 6PM ????

I drive past a few Spar shops on the way home just to go to the Spar at Carlswald Shopping Centre in Midrand. I have been shopping there for quite a few years and it is generally a good experience however there is one negative point...they decide to do their cashier change of shift at 6pm each day...this is one of the the busiest times at this store and queues are often snaking into the aisles.For those of us that work and finish after 5pm...we get to the store between 5.30-6pm. When it is time to pay we get told that this cashier is closing as she has to go home...this is a service business and surely the customers peak shopping times must be taken into account when deciding on the change of shifts...adding insult to injury there are even a few cashier points that closed during this time. With the aisles full of people that are in the queues to pay...this makes normal shopping during this time an absolute nightmare.
