answer:turn it around. what if you took the last one? my point is that someone has to take it. if it is community property, then I say it is “first come, first serve”. Although, it should not be abused. if the first person takes more than their share, then we have a problem. sorry, but I think you just have to find another source of caffeine at this point. EDIT…i misread the description…if it is known that it is “your tea” but you’ve made it community property, then i think the etiquette would be that you get the last one.
