Costco membership comes with some obvious perks — namely, access to the retail chain and its food court.

But according to dozens of Costco workers who spoke with Business Insider, being a member doesn't entitle you to do whatever you want.

While Costco made Glassdoor's list of best places to work in 2017, employees still had several complaints about shoppers' rude and inconvenient behavior.

Business Insider spoke to 49 Costco employees about the things they want to tell members but can't. Some of their responses focused on obvious problems, like members being mean and inconsiderate. But some of the tips were more instructive.

Here's what they had to say.

A Costco employee from Arizona told Business Insider that they wanted to tell members to stop leaving "sample cups all over the floor." "Don't be rude," the employee said. "Clean after yourself."

"Please put back that item that you just threw there," a Costco worker from California told Business Insider. "It doesn't belong there."

Eight other Costco employees also told Business Insider that they judged members who left products strewn about the store.
