<human>: I work at a small convenience store and I've only been here a few months. There's the usual drama here and there between coworkers and just recently, a bulletin was put up saying "To all employees: If you do not sell lottery tickets that customers refuse by the end of your shift, YOU are responsible for purchasing them". 

I'm young and have really no ground to stand on but, isn't there some sort of workers protection policy or something stating that an employer cannot force you to pay for anything unless you are directly responsible for any kind of damage or defamation? Sure, our store loses money when there's lotto tickets that have been printed and cannot be cancelled therefore requiring someone to pay for them but I don't think it's the employee's responsibility to pay for them. 

There's always a risk when operating a business and if you choose to sell lottery tickets, you accept the fact that here and there customers are gonna be dicks and not pay for some tickets so the company has to bite the bullet. Most companies budget at least a portion for losses, correct? Why would an employee have to cover their loss?

Give me the gist of the text in a nutshell
<bot>: My boss wants me to buy lottery tickets that customers refuse to pay for. Is she allowed to even suggest that, like it's some sort of policy?
