Unprofessional services

I m so disappointed with the service of Click store in Brixton. I came in t buy few items as I was going in the medicine section the Manager and the consultant followed me until I got to the till to pay. I was very angry that why are they treated me as the ******** or ***** really especially the Manager Click store policy said any customer that come in their store must be treated special and respectful. I am disgusted how they treated me .
