Drunk spar employee screamed and humiliated us.

Spar, Durban, Saint George's My sister and I went to spar on the 16/12/2021. My sister had a packet of chips we had bought from another shop. We still had the slip with us. We walked in and forgot to mention this to security. When we walked out a staff member shouted for us while we were walking down the passage. We approached her and she started screaming at the top of her lungs about how we stole the chips. We produced the slip which she looked at and she continued to scream at us about not telling security when we entered. During this altercation I realised she reeked of alcohol. I tried to tell her there was no need for her to scream at us as it was a simple mistake. She continued screaming while people stared at us. I took the slip from her hand and said we were leaving. She said my sister cannot leave because of what she did(walking in with the chips) I I finally went to security and asked for the manager. Security told me there is no manager available. I even ended up recording her screaming at us. She humiliated us and threatened us saying we will go to jail.
