Pick n pay delmas they are so rude

I was at pick n pay delmas with my 15 year niece and his father so the boy took stimorol cheapie to show his father on the other side after 5min I heard the manager of pick n pay shouting at the boy "don't come in my shop and still sweets I will **** you" those words made me to be so angry with him meanwhile the boy didn't take those things he's just accusing him then I asked him show me the proof he said his eyes are the proof. The manager of pick n pay delmas is so rude and ****** and it's not for the first time he did this.
