Sheetz review: poor service, possibly vindictive (?)

At approximately 5:15 yesterday (03/04/2020) I had stopped in for cigarettes, the line ahead wasnt very long but there were several people behind me (7). An associate and thw assistant manager (tammy vanatta) were behind the registers until I came to be next and ms vannata just left the register, hampering the service level under the guise of needing to get food orders out, though leaving another associate idle behing the food counter.
Im not positive, though you may find out if she is questioned, if she were acting in a discriminatory nature. It is all on camera: her leaving what would have been a small matter for two registers, the idle associate not working any food orders, just leaning and smiling at something ms vanatta was saying from behind the partition while customers are seeing this.
Hopefully this breach in service is at least discussed with her as it has to be effecting sales.. I spoke to several people that refuse to shop there in the future.
Again I have to reiterate my suspicion of vindictive or unproffessioanl behavior. It is not the first time she's left a line of customers waiting and not replaced herself at the register.. Just the first I know of on camera. Its certainly a great way to elevate competitors business though. And yet I have to suspect her behavior is resulting from a relationship gone bad... And it not with me to be certain
For vido indexing it was at approximately 5:15 pm est on 03/04/2020... I will be visible in a grey parka, greenish ski cap, and using a blue metallic cane.
How is this acceptable from a business standpoint for any reason?
