My 'close friend' stopped speaking to me a few years ago after I dropped out of her hen night. Her DD was to make all the decisions as to where we were going to be staying for two nights, including what activities etc we were to be doing too.
The trip was planned 80 miles away from where we all live, her DD had arranged and booked everything, giving only a week's notice to pay up (this was organised almost a year before the actual wedding!), and had originally insisted that the whole weekend would cost £200.00 each max. She also arranged for the trip to consist mostly of her own friends and, via the WhatsApp group, a few people started to drop out.
Brides DD told everyone remaining we would now have to make up the shortfall for the people who were no longer going, bumping the price up massively (there were originally going to be about 20 of us staying in a large house).
We were also told that we'd be footing all of the bill for the bride, down to the last penny, as the "bride shouldn't have to fork out for her own hen do" . Not that it matters, but it was the bride's second time around.
I quickly messaged friends DD, politely saying that the trip would be too expensive for me, as there was no way it was going to only cost £200, and would be more like £500 after factoring in extra costs, including extra rent, transport, drinks, food and so on.
I was told "ok, don't worry about letting my mum down, but you are still expected to give me £80.00 for your share of the rent for the house"
(I realised that the DD was not only expecting people who couldn't make it pay for the deposit, but also expecting everyone else's bill to go up to compensate for the drop outs!, there by trying to make money so her costs would be cheaper!) CF!
Because I said I didn't think I should pay as it wasn't my fault that she'd booked the house without giving people a chance to think it over, and because the costs were getting out of hand, her mum never spoke to me again after telling me that I'd let her down by dropping out.
For what it's worth, I'd said to her DD that I'd like to take her mum out (with a few others) to a local night out, so she could have two hen do's. This wasn't good enough. Fuck em.
