It's been been a while but I came across a GEM this afternoon.
One of the girls in the department comse up to me and informs me that this lady on the phone wants to know what happened to her payment.
Apparantly, this BRILLIANT woman, realized that since she used the same bank we did, it would be no problem to just get the bank to transfer money from HER account to OURS. But this, of course, leaves one small problem... We have no record of this because she didn't send us a payment by conventional means and she couldn't provide any account information with her payment because... well... who is she going to give this information to... at her bank?
