************** a thing at Hamleys Sandton

I'm very disgusted at the way i was treated by staff at Hamley's Sandton , i went to purchase a LOL doll for my daughter on saturday, i paid and on my way out , already on the escalators to the mall , a young man came running after me ,asking for an invoice, what puzzles me is that i have never seen staff at Hamleys asking for invoice from their customers , was this done to me because a black person is always a suspect ? Do they honestly think I would walk into Hamleys to ***** a lousy LOL doll, I'm very disappointed at the way they treated me , this not only shocked my daughter but it also brought eyes to me from other customers, im shocked to the core and will never ever purchase from them.
