experience bad service this morning with cashier Jasmine at Kiosk,she was so rude and still cannot believe how people can so rude and still see nothing wrong on their behaviour. All I wanted was to pay my Herotel account and told her from on set that its my first time paying at shoprite,what should I submit to her yhoooo she was extremely rude,the manager ended up helping me and she was still rude in front of her.
