A Sandwich From Richard's

A sandwich from Richard's, that's how much you owe me. I want to say a certain amount, but money inflates and I’m suck at math. It was three dollars, but it is five dollars and thirty cents now. I don't know how much I should charge. You did owe me when it was three dollars, but it won't be fair. I didn't ask you to owe me the sandwich. I didn't ask you to delay it for so long.
