Each time my wife or I visited Costco for the past 6 weeks, we've been asked at the check out whether we want to renew our membership. It's not like we get a discount for early renewal so we've been holdiing out. About a week ago, the asking stopped. Ok, I guess my wife must have renewed it. And my wife also thought I must have renewed it. Then I get a call from my ex-girlfriend. Hey hey, what's up? I've been using your Costco membership for the last 9 years (after we've split) and this time, I forked out your $100 renewal because I sure as hell am not going to abandon my shopping cart after standing in line forever. She wants me to pay her back is what's up. Now, I had already taken her off my membership after the split and she knows that. I went to Costco to verify that she was indeed off, and as I understand, I could have only one complementary membership under mine - and that'd be my wife - so how could she still use my membership? So somewhere in Costco's system, something's messed up. Oh well, I get the rebate for the ex's purchases at the end of the year. Only this time I made sure that particular card can't be used. I tell the ex that considering she understood she was no longer on my membership, she should have had the courtesy to stop using it. So I tell her she needs to send me back the card because it's mine, and (jokingly) that we should split it 50/50 for all her unauthorized use. She insists that I owe her 100% and I'm not getting the card back until I pay her back. So I let her keep the ring after we split and she thinks she can walk all over me. Who's the hostage here? Now I'm thinking why I should even give her back 50%. My other ride is the relative wind.
