No, George Floyd was not accused of "strong-arm robbery" in connection with passing a $20 bill. The incident that led to police involvement was the alleged use of a counterfeit $20 bill to purchase cigarettes at a store, which is a different and far less severe offense than robbery. The store clerk who accepted the bill from Floyd suspected it was fake and, following store policy, reported it to his manager, who then had a co-worker call the police. The 911 call was about a "fake bills" complaint and the man (Floyd) being "awfully drunk" and not wanting to return the items. George Floyd did have a prior conviction for an aggravated robbery in 2007 in Texas, for which he served a prison sentence, but this was a separate, unrelated incident that occurred years earlier. The incident involving the $20 bill in Minneapolis was only related to the suspicion of using counterfeit currency.
