i was really upset

abt this whole incident which happened to me yesterday.
I was out with my friend at robinson quey shopping in the supermarket. When my friend and I was at the cashier waiting to pay for our items, this guy that was infront of us took out his things from his basket and after he empited it all, he put the metal thing that read " counter close" RIGHT infront of our things. It was really really REALLY rude. Only the cashier themselves had the right to do that.
We were really shock cause we didn't do anything to offend him. Then we observed that he looked at the cashier in a rude way too. It's really too much.
