A friend and I were once invited by MOH (sis of bride who I'd only met once) last minute to another friends hen do weekend in Newcastle.
We didn't want to go due to money, as neither of us were flush, but we felt obliged as we were good friends with the bride - and we hadn't realised at that point we were last minute invitee's! But it soon became glaringly obvious that we had only been invited by the MOH to make up numbers and costs for people who had clearly dropped out, as we heard the bride quizzing the MOH where certain other people were.
That weekend cost us SO much money for the coach, hotel, meals in fancy restaurants, silly fancy dress outfits, entry to expensive clubs, stupidly overpriced drinks in said clubs, taxis to & from hotel, etc etc.
But what really added insult to injury was that we knew none of the other hens apart from the bride and despite our efforts to get chatting to them on the coach, we were ignored completely the entire time by all of them, apart from when they were demanding money from us to square up for meals/drinks... and I mean rudely demanding, not politely asking.
We even endured dirty looks, whispering & sniggers, shoulder barges leaving no space at for us at breakfast time around the hotel table reserved for the hen party, and then towards the end of the last night they even started leaving us out of drinks rounds.
We'd done absolutely nothing to these people. Even holding back from airing our views so as not to upset the bride, even though she allowed her nasty friends and relatives to treat us like that.
So friend and I left the club on the last night after being omitted from another round of drinks, took a taxi to a nicer bar for a more relaxing nightcap and then went back to the hotel.
When the overly-drunk hens arrived back at the hotel we were called all manner of names for daring to leave, exclaiming that we should've been grateful for being invited along!
The coach ride back was frosty and I couldn't wait to get home. I deeply regretted spending that much money on such an unenjoyable event with people who I didnt know that treated us like unwelcome gatecrashers.
Then once home we were told by the bride we weren't even invited to the wedding anyway, so not sure why MOH had invited us.
I distanced myself from the bride after that ordeal. And I've never been on another hem night. I didn't even have a hen do for my own wedding.
