Number Pet Peeve

ok so i have a lot of pet peeves. one of them is wen someone says for example "do u want 5 or 7 donuts?" 5 or 7?!?!?!? y not say 5 or 6? another one " give me 8 or 10." pic one fer heaven sake!!!!! or say 8 to 10 that would at least make sense. but 8 or 10?!?!? that just sounds dumb.
