"Legit the worst job to do. I just find it boring walking around putting stuff back on shelves," said another.
Other employees found it particularly annoying when customers put perishable items on shelves, instead of back in fridges or freezers.
However, some TikTok users were left puzzled, pointing out to the employee who filmed the clip that it was part of her job.
"Isn't this what shelf stockers do?" the customer asked.
"Yea this job is technically meant for front end [checkout]," the woman, who is a nightfill staffer, responded.
She added it "definitely would make it easier if people knew how to put sh** back".
"Or don't grab it if they don't actually want," she continued.
But other employees expressed how much they enjoyed the task.
"I used to LOVE this job hahaha," one woman wrote.
"I love dumpies and because ur on a mission I find customers don't really ask me anything," another added.
