We are friends with a couple for a long time. Since our children leaving home, we have been spending more time with each other. Slowly I realise that they are both plutomanics, one more extreme than the other. The need to hold on to their money is of utmost important. More recently, we have decided on an expensive purchase for the 4 of us (I don't want to say what it is in case they read this). As they took so long to decide whether they wanted it, by the time we were ready to purchase, the price went up by £320. I swallowed this, not wanting any bad atmosphere between us and I went ahead and made the purchase. It is only money I thought, it's not worth ruining a life long friendship. I made the purchase and gave them all the receipts along with my bank details for them to reimburse me. I was shocked when one of them queried how I paid for it and said that as I paid for it by credit card, I will be reimbursed a month later!
To be honest, I don't really care when they reimburse me, but the cheek of it has left me seething. Now I don't know how I feel about seeing them again. How should I deal with this? I need to clam down.
