A question for experienced BPers. How do you ensure that the Walmart cashier enters the right information? Usually I hand over the CC and he enters all the information. The receipt does not print out the entire account number it BPed too, only the last 4 digits, so there's a chance that the cashier can mistype the account.

Has anyone experienced problems where the Bill Payment goes to a wrong/different account? How do you resolve that situation, and is it a common occurrence?
