AutoZone

I went into the autozone on Buena Vista road to get a quart of oil got my oil went to the cash register to pay and the guy at the cash register told me to go to the other line that they would take care of me fine so i go to the other line which the sign said it was for returns and other stuff but the lady at that register was waiting on some one and had just finished ringing them up so i walk up to pay for my oil and the lady tells the guy that she is going outside to help a customer now i'm standing there with no one to ring me up so i stood there for a minute to see if someone would wait on me nothing happen so i put the oil back and left.Now i don't know why the first could not ring me up and i don't know why the lady couldn't take one minute to ring me up but that is just poor customer service.
