Paying it up on clicc outings

Myself, and a few other people at clicc are putting up a lot of extra cash that we don't have to. I know Aiko and Chris consistently puts up at least 10-30 bucks more than they should, and I put up at least 5 bucks more than I should. My number doesn't compare to theirs, but the point is, this shouldn't happen. On top of this happening, Aiko even assumes some people will not pay as much and fork out the extra $10, and still we don't have enough money for the bill. To help those who aren't great at math, here is how things break down.

For every 10 bucks you spend on food, its 83 cents for tax, and its 1.50 for tip. Now, if your meal is 5 bucks, just half it. so it'll be 41 cents for tax and 75 cents for tip. However, its best to just round it up. Say for 10 bucks, think about paying $1 for tax, and $2 for tip. So basically for a $10 meal you should pay 13 bucks at least. This goes off of the cali tax of $8.25% and a tip rate of 15%. If you feel the waitress is awesome, go 20% or 30% if you want.

For example, if you're meal is 34 bucks, that's 10 + 10 + 10 + 4 right? so you have to have this much in tax -> .83 + .83 + .83 + (.83/4), and this much in tip 1.5 + 1.5 + 1.5 + (1.5/4).

I hope this doesn't offend anyone, but for those of you who under pay, please be considerate of your friends.
