7 Things Grocery Clerks Wish You Knew About Self-Checkout
Self-checkout lanes were designed to speed up your shopping trip—but only if everyone uses them the right way. Grocery clerks see the same mistakes over and over, and many of them slow down the entire process or cause unnecessary headaches. Here are seven things they really wish shoppers understood before stepping up to the scanner.
Not Every Item Is Meant for Self-Checkout

Loose produce, bakery items without labels, or anything needing age verification often slows the line. If your cart is full of tricky items, you’ll actually get out faster by choosing a staffed lane.
The Scale Is Extremely Sensitive

That bagging area warning pops up for a reason. Even lightweight items—like gum or a receipt—can trigger the scale. Set items down gently and wait for the machine to register each one.
Don’t Start Bagging Before You Scan

Clerks say this is one of the biggest holdups. Bag only after scanning to avoid weight mismatches and constant “unexpected item” alerts that require employee approval.
Keep Barcodes Visible

Hold the barcode toward the scanner as you move the item. Spinning products around or guessing where the code is wastes precious time and frustrates everyone behind you.
Frozen Items Don’t Always Scan Easily

Condensation can make barcodes harder for the machine to read. Wipe the package quickly or angle it slower over the scanner for a smoother pass.
Don’t Walk Away Without Checking Your Change or Receipt

Self-checkout errors happen. Whether it’s missed items, double scans, or short change from cash transactions, a quick review saves time—and a return trip—later.
If You Need Help, Just Ask

Self-checkout attendants aren’t judging you—they’re there to help. A quick question can prevent bigger issues and keep the whole line moving.
