vending machines

I just hate this vending machines... They only really work if you have coins... with bills it always has a problem... no bill, except when just given by the bank, it is in PERFECT STATE...

So now... I am here... in my office, fighting with my jobs (compiling, compiling, error, error...) with an URGE for coke (soda caffeine... sighs...), without coins and that STUPID vending machine doesn't accept none of my bill... sighs...

back to work, without coke...
