The Rudest Things You Can Do As A Costco Customer

Costco is designed to be efficient, but the experience depends on everyone sharing the space respectfully. Shopper habits matter—the smallest things can make the environment feel more chaotic.

Many people don't realize their actions disrupt the flow for others. Be aware of these common mistakes so you can shop thoughtfully and make the trip smoother for everyone around you.

Blocking aisles with your cart

Aisles at Costco fill up quickly, and a single cart left in the center can stop traffic entirely. It forces others to wait or squeeze around.

It's important to be aware of your cart at all times, and don't let it block anyone's path.

Samples are popular, but lingering at the station slows the flow and frustrates those waiting behind you.

Take your sample and step aside, so others to try it without crowding. Enjoying the sample doesn't mean you have to be in everyone's way.

Checkouts are busy, and cutting through or slipping ahead of others disrupts the order people expect. Even small shortcuts feel disrespectful to those who have been waiting.

Stay in your line and be patient. This will prevent confusion and keep the process fair and predictable.

Costco's return policy is generous, but misusing it creates problems. Returning heavily used items or demanding exceptions places strain on employees who must uphold the rules.

Treating the policy with respect keeps it fair for everyone. When it comes to returns, use common sense and be kind to the employees.

Abandoned items create extra work and can even lead to food waste if perishables are left out. Placing unwanted products back where they came from helps the store stay organized.

It also prevents employees from spending extra time sorting misplaced goods. It doesn't take much of your time to return an item that you don't want anymore, and it makes everyone's lives easier.

Opening items to test them or inspect contents damages products and creates losses for the store.

Using displays, reading packaging, or asking employees for help is a better approach. It shows respect for the merchandise and the people who maintain it.

Costco employees handle heavy workloads and constant customer needs. Speaking rudely, dismissively, or impatiently makes their job harder and sets a negative tone.

Polite communication goes a long way. A simple thank you shows respect and reminds employees that their efforts are appreciated.
