The fighter pilot's tip calculator! Even if you're not a fighter pilot, you can now dine effectively in large groups like fighter pilots do! Go out to eat with your friends, lay out the rules of engagement: eat well, drink well, be prepared to split the bill evenly, and take care of your servers.
When you get the bill, just enter the amount of the bill, and the percentage of tip you want to leave. Combat Split will figure out an even split of the bill and round up to the nearest dollar (or whatever your local currency is). Everyone's happy (except salad-boy) and the server/waiter/bartender gets the tip they've rightly earned by putting up with your large party.
If you're a fighter pilot, you know exactly what this is. Math in public is less fun than being Snacko. Get this to jettison that pain.
