Another Black Friday has come and gone and retail workers could not be happier that it's over. While the checkout line wraps around the entire store, most of us try to keep it moving quickly, but unfortunately, customers insist on making that as difficult as possible. Here is a list of 11 things that retail worker are sick of experiencing on Black Friday.

1. When a customer asks for a gift receipt after you've already completed the transaction.

2. When a customer asks if the chip reader works after you've already told them to swipe.

3. When 9 of the 10 items a customer brings to the register don't have tag.

4. When a customer calls your store on the busiest shopping day of the year to ask you what your sales are.

5. When a customer is denied for a store card and they act like it's your fault.

6. When a customer walks in two minutes before close even though you've been open for 12 hours.

7. When a customer asks if you have a particular item in the back.

8. When a customer swipes their card after you've scanned one of their 40 items.

9. When your entire store is already 50 percent off and they ask you if you have any coupons.

10. When an item accidentally scanned twice and they are sure to let you know before you can lift your hand to delete it.

11. When a customer walks up to your register and they are on the phone.
