Poor counter staff training at Dollar

Staff tired my card my bank did not allow the payment. I called my bank they said i can try again they will authorise it now, but staff at counter said he can not do it for next 24 hrs as this is system restriction of Dollar that it will not allow the same card to be used till 24hrs are lapsed. He advised to get a car from next counter. I was waiting and he went off duty during this time I went to the counter and next person processed and used the same card. the first person did not even try again despite my frequent requests.
