Actually thinking about it, we were invited to a party a bit like this last year. We were invited for 7.30pm on a Friday evening to a cricket clubhouse.
It was a mad dash for us to get home from work, sort dc with food (McDonald's), get changed & get back into town to the venue
We didn't have a chance to eat & it didn't say anywhere on the invitation that it was drinks only.
There was a welcome drink when we arrived & this was topped up once if I remember correctly. After that it was a paying bar.
I kept waiting for SOME sort of food to appear...nothing....we were foraging for crisps / nuts at the bar & they had nothing either.
At around 9.30pm a birthday cake appeared & it was sliced up but I can't bear to eat sweet stuff on an empty stomach as it makes me feel ill. It also meant that I barely drank as was v conscious of empty stomach = getting drunk & headache. There were lots of people who went for it & were pretty legless by 11pm
We left earlier than usual for us & went to find a takeaway away. It was a milestone birthday & we'd spent a far whack on a very nice present + a taxi in & out etc
I was v v surprised by the hosts choices & it's not a party I particularly enjoyed as by that time on a Friday night I was tired & hungry.
