“I paid for my friend's 4 cocktails because splitting evenly is 'easier for everyone'”

Okay I feel genuinely bad even typing this out (she's one of my oldest friends and normally the most generous person, like she once drove two hours to bring me soup) but here's the thing. Six of us went to dinner. I ordered a $16 pasta and tap water (I was driving). She ordered two appetizers to 'share' (nobody else touched them, they sat by her plate) plus FOUR $14 cocktails. When the bill came she goes 'let's just split evenly, I hate doing math at dinner', and everyone nodded because who wants to be That Person? So my share jumped to $61. Mine should've been like $18 (maybe $22 with tax and tip, but still). I paid it. I smiled. But this is the third dinner in a row this has happened and I looked back at my bank app and it's real money.

Let me lay out the actual numbers, because 'four cocktails' is doing a lot of work here. It was three cocktails ($42) and one mocktail ($9). The two 'appetizers' were shared plates I ordered for the table; four of the six of us ate them, which the plaintiff would know if she'd looked up from her phone. Across the last three dinners I have paid the tip in full every time, that's roughly $38 I absorbed that nobody split. Even-split is the standing group rule we've used for two years, and by my math it has cost me about $15 net over those three nights, not benefited me. I'm the one down money.

I mean (and I hate that I have the receipts, but I do, because I panic-screenshot everything), the mocktail was still $9 I didn't drink, so that's four glasses either way. And the 'you covered tip' thing is lovely except splitting evenly on a $61 base is what created the tip you're bragging about. I'm not asking to be difficult. I'd just love to itemize once. Just once. Then I'll never bring it up again, I promise.
