How do you handle the bill when you go out with a group of people?

Some drink, some eat a small meal and have no alcohol, some eat a large meal and have alcohol, some have coffee and dessert, some don’t, and everything in between.

I rarely go out with a large group except when it’s a work thing, and in those cases the job pays. I did go out a few months ago with a breakfast group from Facebook, and there were about 20 of us for lunch (yes, lunch even though it’s a breakfast group haha). Some had three drinks, some had no drinks, we all shared appetizers and some people had dessert and coffee and some didn’t. The total including tax and tip divided by the number of people came to $50 per person, which is a lot to spend on lunch. To divvy it up by who ate what would have been very hard. One lady had three drinks, coffee, dessert plus her meal, some probably had no drinks. Drinks were at least $10 each so the lady with the three drinks had over 30 dollars in alcohol alone.

I saw this on the site Social Q’s today. People were talking about splitting the bill vs. “subsidizing others’ choices.”

I’m not asking about the luncheon I attended specifically, because it’s over and everyone paid their share and it was fine. I’m just curious how other Jellies handle the situation of a large group going out to eat and how the bill is paid.
