Be experience Bervely

I started working by Portside building recently and I really like Kauai however I've had so many bad experiences with a cashier named Bervery on her tag and on the slip it shows "Nosiphiwo" ...the first instance she gave me a ice coffee instead of berry milkshake I ordered, second instance I was being friendly to her not focusing on the past but she had a sticky attitude where when I felt like never going back to buy there again however I went again she ****d being friendly andthen make rude remarks when I walked away ...I really like the shop but that one employee is not so nice ...I don't have a problem with someone trying to do their job but being kind is free and won't cost her nothing ...I never reported it before because I didn't want her to be in trouble but my experience in that shop is becoming worse and worse each day ...I've never met someone so rude and full of bad attitude
