Zara complaint: Rude employee

I was shopping with my friends yesterday at kings plaza mall, we entered Zara and shopped around. It was a group of us. My friends sister was holding the line for herself and her sister. We were called up next by the rude cashier that shouldn’t even be the front face of Zara. Disgusting behavior. He treated us horrible. He didn’t even great us. He waved for us to go over and without a hello or anything nice to say you can tell by his demeanor he wanted to pick a fight. His first words to us was did you cut the line? We said excuse me ? He said you cut the line. We are not little kids. We are all grown business women that don’t need to cut any line. My friend replied to him saying excuse me I didn’t cut the line my sister was holding my spot. He was nasty about it and unprofessional. He def wanted to pick a fight because he didn’t stop. My friend made a comment on how people are annoying if they complained about her sister holding her spot and instead of him being the bigger person and being an employee minding his business on what we are saying to one another he made it his business: he said what did you say. I said you heard what she said and it wasn’t about you: I said my friend clearly said people and you are one person. He threw our stuff down on the counter and refused to ring us up. Now i don’t know what his issue is. I don’t know if this is discrimination against us being Muslim? But he wanted to start with us for no reason from the minute he called us over. He refused to give us any service. His co worker jumped in-line and rang us up because he refused. Now with Zara allowing this to happen is very upsetting. We buy all of our clothes from Zara and our children’s clothes. We have been shopping at Zara for years. We have never been disrespected or treated the way we did yesterday. Very disappointed I hope this gets solved before it gets worse. I have my receipt with me if you need to know who the employee is. He was the only male cashier yesterday . I regret even continuing my purchase. I should have threw my stuff and left
