The store I go to never checks ID... given they know people. Hell after the first couple of time they don't even check receipt. 

Actually I think gamestop long time ago, only checked receipt information and asked for your phone number. 

Lol, I doubt an LA store would ever be able to do that. Exception not rule. Though, im sure technically thats still policy.

It may have been a joke, but in the business, that's a fatal mistake. You don't even joke with customers public/private information, and that's why she got nailed for this. Customers can act poorly, but as an employee, no matter the frustraton you have to keep a level head and act professionally. She did not.

Both people were in the wrong here.

The person who pisses me off the most? The idiot cameraman.

A manager, who represents that establishment and is supposed to lead by example should NEVER be making jokes at the expense of a customer.

Her sarcastic attitude alone should have her bumped from her position. It is incredibly unprofessional.

If you were at work does your boss have no issues if a customer walks in and you begin poking fun at them?

She was speaking to his in an incredibly sarcastic tone the entire time. Plenty of people would have become very annoyed.

There is an expectation of proper business ediquette when you walk into any establishment. Whether right or wrong nobody speaks to a customer that way. That is a fantastic way to lose business.

If she hasn't already been, she should no doubt be fired. She embarrassed not only her co-workers that night but also ownership as she is a reflection of that Gamestop.

Come on, the "sarcastic" responses are about all you can do in that sitaution. If you dont say anything your wrong. If you say never come back youre wrong. Her responses to him before he walked away were fine. The joke was wrong and in bad taste but not fireable in my opinion

unless the purpose is to allow strangers to show your infomation to other strangers so they can harass you, you're fighting a lost battle.

There is actually zero room for sarcasm with a customer and the jokes (hers especially) were absolutely grounds for termination. I am sure you wouldn't like picking up a game or buying clothing somewhere and the clerk making a joke at your expense. It may seem funny when it isn't directed at you, but even if this type of situation arised it would be grounds for discipline:

Customer: "Hi, I am picking up my copy of GTA 5."

Clerk: "Sure, may I see your ID?"

Customer: "I'm sorry, I forgot it. I have my reciept though and it is paid off in full."

Clerk: "Sir, you would think it is well knows that if you are picking up a MA rated game that you would need to bring ID to prove your age."

That scenario ends up with the customer becoming the butt end of a joke and possibly in front of other customers. Now you just embarassed your customer. The proper response would be:

Clerk: "I am sorry sir. Store policy states that I cannot sell this product to you unless I can validate your age."

She is paid to do a job. She is paid to act in a professional manner. If she doesn't like the rules then she can go home and look for another job, which I hope she is because with her attitude she shouldn't be working with customers in any form.

That is exactly the purpose of a business card. Except, change harrass to contact but if it happens adversly you cant really say you didnt expect that. 

First of all there was an issue before the video starts. Hence the video being taken. Secondly you cant dedicate your time to a problematic customer when there is a sllew of other people behond them. For a person like that the best thing to do is complete the transaction as quickly as possible and send them on thoer way. You cant just spend your time begging for the customers business and you cant just ignore the customer. Her responses up till he walked away were fine.
