harressing a teenager

My daughter and I visit Mugg and Bean on the go at Broadway , Durban North at least 3x a week ,on Monday the 02 November we went there after school and my daughter went in to get chai tea , one of owners (Pierre Barnary )accused my daughter of paying him with a torn R100 note the week before and he harassed her when she went in for her chai tea today ,I am totally disgusted with the service and the manner in which these people treat females especially a teenager , I appeal to all my friends and family to refrain from supporting people who have no respect for paying clients and especially no respect for women . I gave this man a new R100 note and told him he lost a customer today and I hope he get richer with that R100 even though we did not give the torn money last week , When I saw him chatting with my daughter I noticed her body language change and saw such fear in her which horrified me as a mother , couldn't this man ask to speak to an adult instead of making a child feel like a ***** , I'm shocked that people owning a franchise don't train their staff to identify torn money and a week later harress clients who regularly support their store
