I wasn't suggesting that they go total up what everyone ordered at the end of the meal, but simply split the bill in half and hand one to each party, but I imagine that one could have separate checks set up in the manner above, it just seems a little bit precise, and cheap IMO.
Kinda like having a tipping formula that starts with 15% and adding or subtracting based on certain events and guidelines??? Yeah, I agree that it seems a quite a bit precise and cheap... If it's a couple of drinks in a bar, then one of us usually just picks it up and next time someone else will. Meals, usually just split the check... If I had the lobster or a lot more whiskey, then I'll throw in a few more bucks. No biggie. K (Sorry, couldn't help pointing it out...)
Point taken, but I think there's a distinct difference, in the case of a split bill, I am dining with someone that I'm presumably friends with and will see again on a regular basis. If there are huge discrepancies in the paid versus owed amount, it can be settled later, while in the case of a gratuity, 99% of the time, it is a one time transaction. If there's a pattern of inequity in the first situation, then I will address it.
