This. It's not even about whether one can afford things, but the unfairness of splitting the bill. I have an anecdote where a friend of mine had 2 glasses of juice, while her friends were drinking wine and all sorts. When her part of the bill was $4 she ended up paying $50 (currency approxm, but you get the point). Even with similar incomes, as young adults in our mid-20's, working hard for our money, we'd like more control over what we end up paying for.
