"Local casino issued a $20 free play coupon in the newspaper with no expiration date. I talked to the newspaper delivery guy and asked him about that copy and he told me he’s got 100’s of them in the van as they were a few days old now. I got all of them, clipped out the coupons and proceeded to make $19.50 every day after work for around 500 or so days.
Not quite years, but pretty damn close. The casino never printed a coupon without expiration/one per customer rules ever since."

Most of the time, the operator knew the number was a pay phone. After ~5 tries, we would get an operator who didn’t know or check that it was a pay phone.
