> It's a bit like hating numbers, and saying "What do you mean by 'three'; what is it - three volts, three amps, three metres?

No, it’s a bit like saying “for chocolate M&Ms, 3 obviously means 9, to compensate for the fact that they’re much smaller than the peanut ones”.

Can I get 3 M&Ms? Obviously I mean 3 serving sizes, how else would you measure M&Ms?
