Unpleasant attitude from employee

I'm extremely not happy with the attitude i received from one of the employees at the parcel counter. I had a pack of nappies and i was willing to quickly put them by the parcel counter so i can quickly rush to the kiosk to buy airtime. They have this new thing of giving people a basket with a number. It did not make sense to me to take a huge empty basket just to buy airtime. So i asked to be given something smaller and the guy was like "just take the basket, if you gonna put this here (referring to the nappies, that he already took, now pushing the basket towards me with so much attitude) you going to take this basket. I was literally so shocked at his attitude that i decided I'll take my nappies back and leave the shop.
