Disappointed at branch of Shoprite Ermelo

On the 5th of july we went to shoprite in ermelo to buy some groceries and walking past the beverage freezers we saw castle non alcoholic drinks in the freezer next to cold drinks, and thought to buy some, since its alcohol free. Getting to the pay point the cashier told us that she can't rang it up, since its castle beer, trying to explain to her it's alcohol free, she called on the manager. The manager then said who ever packed it packed it wrong. My argument is that first the is or was no sign or paper prohibited the sale of that particular product nor was it sealed of by freely displayed and open for anyone to take. Another this that I observed was that no social distance is maintained at the store, the markings are there, but only 3 of 4 lines, and nobody is making sure that its kept to social distance. No wonder they had a covid case before.
