With Black Friday less then a week away, retail workers begin preparing for the biggest shopping day of the year. Here is a list of nine things retail workers are guaranteed to hear from customers.

1. After working a 10-plus hour shift, a customer will walk up to you and say, "Excuse me, can you help me?"

2. Customers have been waiting in line for nearly half an hour when another customer will walk up to the cash register and say, "I have other stores to go to, can you check me out next?"

3. That same customer doesn't move and says, "But I only have one thing!"

4. The customer that will say, "I forgot my coupon at home!"

5. Even better, the customer that says, "Is there some kind of sale going on today? There are so many people here."

6. Or the customer that's complaining loudly about the price of something that never goes on sale.

7. The mother who brings her children Black Friday shopping, but asks if you can watch them "for just five minutes."

8. The customer who will threaten to take their business elsewhere because they don't get their way.

9. And the customer that has spent hours looking for an item that's out of stock who says, "Are you sure it's out of stock?"

So to all of the retail workers out there, I wish you good luck this holiday season. Don't let customers get the best of you.
