being very convinced by mars bar ads, i believe that it can be a replacement for my thursday lunches but i obviously can't operate a vending machine since i keep pressing the wrong buttons.
all i want is a mars bar that costs me 2.50(-.-) but i always without fail, get something else like skittles.
let me explain why skittles is a terrible meal replacement.
at first you'll enjoy it and think to yourself "oh. who cares if i didn't get that mars bar. this is pretty good"
after about 20 skittles you start thinking "all of them taste the same now..i better press the right button next time. waste of money"
also, the taste of skittles does not leave your mouth for...a while.

so, a mars bar may not be a good meal replacement but skittle is even worse.
nutella is always awesome. no justification needed.
