Steers bad service

Hi very disappointed at king shaka international Airport steers I work there at king shaka international Airport I went at 14:10 to buy a ice cream from steers the plain cone which is R6.90 I was told there is no ice cream I must go to Milkylane next door but I do not like milky lane ice cream so I never purchase them right behind was a lady that wanted ice cream at steers and there served her which is funny how can u treat staff different I perhaps think the staff at steers king shaka airport need to catch a wake up call and this is really not on like I wanted credit I was paying for the ice cream and I truly don't like what the staff at steers did
