Spar Tops Dunbar Cato Ridge so rude!!!

Spar Tops Dunbar's Centre Cato Ridge has staff, Spamandla and Anele, who instructed the cashier not to sell beer to me simply because I questioned why would this particular Tops have different rules compared to all other Tops across the country. I eventually left without what I came to buy. Am fuming right now... never have I ever been disrespected so much. Staff downright rude!
