Went to dinner with 5 friends. I ordered a $14 salad and water. Others ordered steaks, cocktails, appetizers — the bill was $380. They wanted to split it evenly: $76 each. I said I should only pay what I ordered plus tip (~$18). They called me cheap and said "that's just how group dinners work."
We always split evenly — it's simpler and everyone knows the deal. They agreed to come to an expensive restaurant. If you can't afford it, suggest somewhere else next time. Nickel-and-diming the bill is awkward and makes everyone uncomfortable. It's about the experience, not the exact dollars.
