      Answer1:I would go to any random store and ask if they can give me change for a $20 so I wouldnt have to deal with it.
      Answer2:well go in and speak to the manager they can pull you up on the register from the time that you purchased the coffee and see you were there you need to inform them of this and get real money back because it is rightfully yours
      Answer3:You have 2 choices:1. Risk it and go back to complain to the manager about it. 2. Simply accept the probability that the fake money was given by another customer and is not really the cashiers fault.
      Answer4:The best advice I can give you is to learn from this. What seems to have happened is that Starbucks have passed off fake [forged] money to you. They probably did this on purpose knowing the money was fake.Im sorry that since you do not have a receipt showing the original transaction, then you have no way of proving anything. The other thing is, even if you did have the original receipt, Starbucks could argue that the notes you have are not the same ones they gave to you in the form of change.Both here in UK and in the USA there are million in forged [fake] money floating about in the system.The way to deal with this problem in future is to make every transaction using a bank card - Switch Card or similar. Not a credit card. This way you can keep track of how much you spend, where you spend it and since your bank will be tracking your spending, youll have the equivalent of a receipt held by your bank, because it will have paid for the transaction directly from your account by electronic means to the account of the outlet where you spent your money, in this case Starbucks.The link below may help you understand something of the countrfeiting criminal industry - forged US currency is coming in from Korea according to this next link.http://images.google.co.uk/imgres?imgurl...
      Answer5:Youre stuck. You accepted them and probably will have a hard time convincing Starbucks to take them back and if you pass them to someone else or a store then youre committing a crime.
      Answer6:Try taking them to a bank or to the police and handing them in. You wont get any money for them, but at least you wont go to jail for trying to pass off forged notes. You can tell the police where you received the notes, but I dont know whether itll do you any good.There is nothing you can do. The United States currency is notoriously easy to counterfeit, and there are millions of forged notes. So yours is a drop in the ocean.Seriously, turn them in to the authorities and count your losses. Its better than spending them and getting caught and prosecuted.
