Hello how may I help you? Hi, I was wondering if I had any late fees at my local library. What is your account number please? It's 1-800-CONTACTS. You have $30 in late charges Oof. That's a lot. I should probably pay up. Sure. We only accept credit though See, here's the thing: I only have cash. Do you think it would be OK if I just put 30 bucks in the slot where you return books? Sorry . We only accept credit. Can I take a picture of the $30 on my phone and Email it to them or something? Sorry . The policy is credit only for late fees. All right, fair enough.
