This afternoon, was charged $2.99 for large cantaloupe that was prominently marked in two bins in the store $2.50. Realizing this after I left and thought to check the receipt (which I always ask for even though paying in cash), I returned to show it to her and ask for a refund. Without a word, the cashier gave me the coins, offering neither explanation nor apology. Does that mean, 'oh well, I didn't get away with the overcharge this time'?
