cashier has got no manners

I just stop at Steers at Total John Voster, to buy food and what n bad experience yet again, the cashier that assisted me before as well has got no manners does not know how to work with customers at all she is so rude and don't even try to hide it,with the man in front of me you could see she got irritated because he asked for the tap machine to pay for his purchase instead of the normal swipe machine, She does not greed you, i asked her if they have to scream on each other she and the bakery staff not talking literally screaming you can hear the even outside the door,Did i not get attitude from her she puts my food down on the counter and glares at me not thank you come again nothing just puts the food down and turn around and open a container. the counter is always dirty, again there was heaps op sauce on the counter the sauce container is dirty on the nosels where the sauce needs to come out, i have asked 3 times before do they not clean their counters the sauce is dry so long has it been there, after i turned around to walk out of the shop she spoke to the shop cashier about me, i turned around and looked at her and she kept quit and did not even look in my way.And why does she needs to speak in her language in front of customers why cant she speak English so that customers can understand what she is saying. there is no issues with the other steers cashiers, as soon as i walk in to the shop my order is already started to been made, that's how good they know me,She must really be send for proper training she is doing more damage to your store then you know.
