The scene starts when Denzel Washington is picking up Diapers and other items in the Drug Store. He is approached by a man who compliments him on his work on the case and then tries to "pick him up". Denzel gets pissed off at the assumption (especially since he is buying diapers and mentioned his wife as an excuse why he can't go out for a drink), then he storms out of the store WITHOUT PAYING for his diapers.
