I agree! I don't drink alcohol (anymore) but I am a Diet Coke addict. There is a distinct taste difference between DC in a plastic bottle and a can. For what it's worth, back when I DID drink, I prefered beer in a can over bottle too.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
