******* attitude of member of staff at store

I went to this store to purchase some goods, more specifically, some deodorant. I tested one of these and a member of staff shouts out "no testing". So I said to him that there isnt a sign. And he says the sign is above and points to it. I see that that the sign was two metres above me where I think customers can hardly see it. When I mention it to him, he argues that customers do see it. Apart from the lack of professional decorum as this man was shouting at staff in front of customers as much as 15 -20 metres across the aisles, he also lacked any decorum when he spoke to me. Management ought to attend on this.
