I didn’t like the way one of the cashiers spoke to me

I don’t know if I’m being dramatic or what, but I don’t think the way one of the cashiers spoke to me,is how you speak to customers. I decided to go to Boxer liquor(Matatiele branch) the one near the taxi rank . I needed to withdraw a cashsend and I stoop in the queue, as I was standing there one gentleman passed me and I assumed he is going to pay since the other cashier was only assisting people who are paying and not withdrawing. Okay fine, the was a lady in front of me and I asked her if is she also going to withdraw money and she said yes. As she was about to be assisted the gentleman walked towards the till and this is where I walked closer to the cashier and said to her” sorry sisi ubhuti ndimfikele kuqala” I said this because I could see that the gentleman ebezondingenelela but the response I got from the cashier was “nditheni mna?”and I responded and said “ bendikuxelela because ndibona ubhuti esondela “ again she responds and says “ ewe ndingenaphi mna”. I respond and say “ asikho isdingo sokuthi uthi ungenaphi because besendikuxelela “ then she says” mna bendisezonceda usisi(pointing at the lady in front of me) futhi akhomntu ongami iline apha” . As someone who works with people that’s not how you speak with customers worse I was not even rude , I was just making her aware that I got there first because had I not spoken up that gentleman was already infront of me . I go back and stand in the queue and it’s my turn to withdraw money and she asks me how much do I want and I tell her that I need R1500, her response was” andinayo”💀. How am I supposed to know that she really didn’t have that amount after the altercation we had? She said she gave the last money she had to the other cashier. Okay fine, let’s say she really didn’t have money , why didn’t she say anything while we were still standing in the queue like the other cashier who was making the customers aware that she is only assisting people who are laying and not withdrawing 🤷🏾♀️. I tried looking for her name tag but she didn’t have, I don’t like that I am now using the name “cashier “ but had I known her name I was going to refer hot her using her name. I really didn’t like the way she handled the whole situation and even spoke to me even after I told her that’s not how she was supposed to respond to me.

It’s not nice standing in the queue and someone decides to pass and tries to get assisted before you,hence why I was telling the cashier about that gentleman.
