Rude Cashier

So I walk into Cambridge Foods in Hillbrow and as usual there is long queues and some till points are closed. I wait it out in one of queues,then one cashier opens her till. I rush there to be first in line. As soon as I get to her she rudely exclaims ''I dont have change"'. Seeing as I has a R50 note,I wait for her to serve about 3 people behind me so she could get change. I ask her politely ''do you have change now?'',the answer I got left me shocked. ''Are you asking me or telling me,I dont have change!'' First of all its not my problem the cashier opens a till point with no change,secondly the amount of rudeness was really uncalled for. I stormed out and went to purchase somewhere else where they have GOOD CUSTOMER SERVICE. I'll never shop at Cambridge again after this
