coustmer service

so today i have a very bad experience at adidas store in gurgoan ambience mall there i was seeing shoes then i pick one shoe and going to try it then one sales girl came to me and said that it is not on sale i said ok and then ask for my size then i tell her my shoe size then she bring me my size then i wore and return the shoes and she take the shoe and go then i goes to the section where there are football tshirt then i go there and see some tshirt and then se came again and said that these tshirt are not on sale i said ok i know that then she says in a very rude way that if you are willing to buy anything you can buy otherwise you may leave i have other works to do i was like what is this kind of behavior. i am a coustmer you must treat me well i have to right to see the product then made my mind but there the sales girl was so rude that se did not let me see anything
