interfamily warfare

all i asked is if the coffee would be good for the expresso maker and then she says to her dad, well greek coffee...it's the same as turkish coffee...no good for the machine. her dad looked as if to kill her. her mum came to her aid. they all spoke loudly and agitatedly in greek (or turkish?) . i said i didn't mind. i'd just get the best-in coffee instead. i retreated. they were still argueing when i left them in my local corner shop...
