No respect towards their customers

I was shopping at Longtom Spar Lydenburg when I got to the pay point I gave everything for the lady to ring up. Once she ring up my childs cooldrink I gave it to my child to drink. The cashier turned to the person who packed the bags and made ugly remark of my child. The cashier foolishly think that I didn't understand her language well in fact I understood it very clearly. This type of behaviour is unacceptable. Longtom Spar Lydenburg clearly has no respect for other race and to their loyal customers.
