AIBU.
BBQ for 10 (4 couples plus us) of ‘hobby group’ friends in being p’d off that having asked guests to ‘bring what you like to drink’ after spending £150 on nice butchers bbq stuff and homemade salads, sides, nibbles and desserts, we are left with 4 bottles of exceptionally cheap rose (think Aldi lowest price wine) and no leftovers, most having 2nds and 3rds as the ‘food was so good’! They also drank through 6 bottles of DH good Sauvignon blanc!
We would normally go out to dinner with them and spend £100-150 per couple - they are not struggling financially! 1 couple did bring chocolates and a bunch of flowers. 3 other couples just bought cheap wine and beer which was also drunk.
AIBU if told food provided, and being asked ‘just bring something to drink’, you should drink what you bring!
