Everyone should pay

Normally when you have a group and then its Friday night the starting of the weekend . They go to a restaurant where only one has to pay the amount of whole five members in a group . Sometimes it happens like "Oh shit! I forgot the wallet at home or I don't have that much amount of money or my hands are little tied today so I am sorry." You can get rid of these lame excuses if you plan to share the equal amount of money every weekend you go to a restaurant. For example the bill is 500$ you are five people everyone should take out $100 and pay the bill. Its simple :)
