Quicksave Witpoortjie ******* gambling

Today at 11:20 I sent my son (11) in to witpoortjie quicksave to buy R50 unipin. He came out with a R50 hollywood betting slip. I confronted the lady at the counter about this an why she would sell my son, which is clearly under 18 a gambling slip. She got immed. upset and said that im the problem client . I have been a client of them for 22 years and this is how one is threated. The client is always right. except at witpoortjie quicsave it seems.
