This is the thread that keeps on giving, unlike most of the people written about!
We had some old friends that we knew from uni days. He was always known for being a complete tight wad but she would do her best to offset him (however, has been with him for far too long now so she doesn't seem to notice/care anymore). It came to light at their wedding that he had been charging her for eating meals at his all boys house and then keeping the money rather than putting it in the kitty for all the food they bought. The other boys hadn't minded her eating there, as they always cooked bulk food and she ate like a sparrow back then. But they were rather gobsmacked to find out at the wedding reception just how low he could go!
Forward wind several years and same friends had bought a holiday house in a lovely part of the country. It was a property that they also used to let out so we never expected to be priority for an invitation (we weren't one of their gilt-edged invitation type friends; yes, they used to keep those proudly displayed on the mantelpiece when we went round, gilt-edged invitations, that is, not friends!), so when we were finally invited he spent ages telling us how whenever they had friends or family to stay, they would be losing rental income. So we go there armed with all sorts of food prepared (pasta sauce, soup, cakes, more cakes...) and a whole case of wine & champagne for a 4 day visit plus a gift for the house. We arrive early in the morning and because it is a rental, they don't keep food there, so need to go to the supermarket. I (foolishly) volunteer to go with the husband and when we get there he 'realises' he has left his wallet behind. No matter, I've got my purse so we're okay, I say. He then proceeds to load the trolley not just with enough food for while we're there but also for later in the week when they have other friends coming to stay AND a large packet of disposable nappies for his DD. Bill was over £200 (a lot for now, let alone back then). Never once offered to reimburse me.
Whilst there we also took them out for a meal for all of us plus kids, which we paid for. Nothing fancy, but it added up. We had offered to take them to a nice new restaurant nearby that I had heard about but they said it would be too much faff to get a babysitter. Turns out they went there with the friends that came later that week.
Not long after, we also bought a holiday home in another part of the country. Because they were some of oldest friends and partly behind the reason we had bought in that part of the country, they were the first people we invited to come stay with us. They brought a small gift for the house and a bottle of wine. We don't let people go hungry when they visit us, as anyone who knows us would tell you (my DM calls me the Quartermaster, given how well stocked we usually are!). So having fed & watered them well for a couple of days, we go out for lunch, just a bog standard pub lunch, not much alcohol consumed, so not a huge bill. No offers to pay so we go halves.
We have them to stay several more times, on the last visit don't even bring us a bottle of wine, and never offer to take us out for a meal. Always myself & DH doing the cooking etc. The final straw was on the morning my DH suggested to the other man about going for a bike ride. He was supposed to be looking after their very young baby, as he told me his DW had had a very bad night and so he was letting her have a lie-in. I volunteer to look after the baby as well as the other 4 DC's. As soon as he leaves baby starts crying but doesn't need changing and I don't want to disturb mum so I think it's probably due to being left with someone he's not used to and do my best for the next hour and a half to console an inconsolable child. When he gets back and I tell him how upset child has been, he looks at his watch and says oh yes, he was due a feed at xx o'clock (an hour ago). Wtf! If he'd told me I could have taken him up to mum (he was still breastfeeding).
Many, many other examples of his stingy user-i-ness personality but I'll leave it at that!
Finally wiped off the 'mug' sign that was written on my forehead and let the relationship slide.
