So when you are at GS and someone comes and returns a bunch of baby stuff as an ID return, it'll often prompt to have the guest insert a card. I can't remember the exact wording, but I am sure you all know what I am talking about. I've been told this is happening because they met their limit of ID returns. They other day, the computer rejected the guest's cards (I wish I could remember exactly what it said) and the screen wouldn't allow us to scan another thing. I called over the SETL hoping she would send the lady away, but she didn't. Instead the pile was returned one by one. Ugh. Please tell me more about what is really going on with the POS. Do you think it rejected her card because she doesn't pay for things at Target with them or because there is something else happening?
