Disappointed at standard of service of the fuel forecourt

This morning I bought a croissant from the Woolworths Forecourt at the Engen in Paarl in the Main Road opposite Terra Mare. The service this morning was apphauling.

As I bought the croissant, it was priced at R29.80 and then at the cashier it was R30.80. I informed the cashier and she just continued as per normal. Then I bought the croissant and went back to the deli to advise that they need to change their prices on the display and she just stated that that is the price so that is that??? Then I asked her to please change it to the correct price so that other customers are aware that this item is R1 more than what is advertised. As I walked away, she told her colleagues I am going on about a R1.

To enjoy patronage at Woolworths, there is an expectancy of a certain standard of service when addressing customers and I honestly was disappointed this morning.
