it happened in aisle 3!!
woman in line ahead of me (to cashier): what did you just put on your hands?
cashier: lotion, my hands are dry.
woman: did you put that lotion on 'cause you think my money is dirty 'cause my money is NOT dirty, miss.
(cashier continues to ring woman's order, ignoring her comment)
woman: i said MY money is NOT dirty, miss.
cashier: i didn't say it was, m'am.
woman: ok, then.
