Can limits be placed by a merchant on which currency notes are accepted as legal tender? [duplicate]
Can they reject a hundred dollar bill as a payment of debt?! No. A creditor cannot refuse payment in cash, whatever denomination you use. HOWEVER, when you're buying stuff - you don't owe anything to the business owner. There's no debt, so the above rule doesn't apply. As long as there's no debt in existence, the matter of payment is decided between two parties based on the mutual agreement. The demand not to use large bills is reasonable in places like 7/11 or taxi-cab that are frequently robbed, or at a small retailer that doesn't want to invest into forgery detection and fraud prevention. So the answer to this question: Is it the case where this practice of accepting small bills and   rejecting large bills is perfectly legal? Is yes. You can find the full explanation on Treasury.gov, including code references.
