I agree with Amberleaf 100%
We married in a Scottish castle. We bought the booze from Macro/Majestic and hired staff to serve it at the evening reception. With champagne, wines, spirits and some liquers for welcome cocktails, it was not cheap. If I'd have had to pay corkage or the venue had insisted on providing alcohol at hotel rates, I would have bitten the bullet and stumped up, cutting costs elsewhere as need be.
There was no fucking way that I would have expected guests to pay for their own drinks, especially given the travel/accommodation costs (although we put close family/the wedding party up in the castle for the weekend at no cost).
My priority was feeding and watering our guests quality food and drink and ensuring it was plentiful. The same as I would if I hosted a dinner party/BBQ. I very much saw the reception as a party to round off the celebrations, rather than a separate thing. People who attended were there all day (or some the weekend)
We still had the day we wanted-well to be fair, it was more like an extended celebration over the weekend-but we invited those who were important/relevant to our lives-not distant relatives we hadn't seen in 20+ years, so in that respect, we cut our cloth accordingly.
I have been to pay bar weddings myself, and despite my own strong feelings in regards to my own wedding/priorities, I don't have a problem with paying for my own drinks- but this seems to be a new thing over the last 10-15 years, IME. In the 80's/90's most weddings seemed to be either a free flowing bar or an amount placed behind the bar-and when it was gone, it was gone.
I don't "look down" on B&G's who do thin
