I have only a few weeks ago.
It cost an absolute fortune in petrol to get to the wedding venue.
2 nights bed and breakfast £350. Too far to travel the morning of the wedding or after the reception so had to stay over for it to be worth going at all.
Outfits, shameless couple asked us to pay for DH and DS outfits (even though they were in the wedding party)
It was the wedding of a close relative so couldn't just not go.
The hotel was in the middle of nowhere so no choice to go off for food elsewhere night before the wedding unless we wanted to drive 45 minutes, so had to have an evening meal there which cost a lot.
There, we discovered that a pint of lager was £5, a small glass of the cheapest wine was £6. Soft drinks were about £3 each. They even charged £1.50 for a splash of a mixer!
One round for a family of 3 was costing roughly £15 depending on what we had.
It was ridiculous considering we were there for 2 days.
My friend and I warned a relative who was traveling up on the morning of the wedding about the prices. God love her she turned up with several bottles of wine and some vodka, all cleverly wrapped up so the lids were still removable, and put them inside bottle gift bags. She also brought a couple of packs of fruit shoots for the kids.
We kept them under the table posing as gifts, and poured under there discreetly, then took them all away with us at the end of the night.
We paid for soft drinks/mixers and lagers so we didn't completely dodge paying for drinks. It just allowed us to relax and not worry about how much it was all costing.
Felt no shame as we spent a fortune at the hotel anyway, room, food and we did pay for some drinks, and we felt their prices were really unfair considering the drinks were only average supermarket type wines and beers, nothing special. I wouldn't have done it if they were more reasonable.
