I had attended the Camberwell Green branch and been looking for Manuka Honey, Vitamin C and Apple Cider Vinegar for a boost to my immune system due to continuously being sick. I was approached by a man called Claver who wasn't in uniform so i was a bit skeptical when he spoke to me. He said "can I help" in an aggressive tone and I declined. He then went away but I could see him watching me. I asked to be left alone as I felt intimidated be then left. Once I had paid and was leaving he ran over to me shouting STOP STOP !!! in front of other customers. He then grabbed my bag pulling me to one side and began searching saying I had stolen. At this point I started to get upset and felt close to tears. After finding nothing on me he shouted "your ban from the centre don't let me see you here again or else I'll call the police, stupid women" I saw him laughing on his mobile speaking French when I walked past 10 minutes after. As I can speak French what he had said was too Volga to repeat. I have contacted the police and my local news paper about the incident as I believe this needs to be highlighted so nobody else experienced such abuse from a man. I don't normally complain but this was just too much for me to keep to my self and remain scared to speak about.
