スタバカ日誌〜One More Chance〜



It's been more than a month since Starbucks Japan introduced its One More Coffee campaign.

One can get another cup of drip coffee for 100 yen at any Starbucks on the same day. Given a tall cup costs 340 yen in Japan, I feel worsed off if not taking this advantage. Is the marginal utility of second cup higher than first?

During final exam week I was totally caffeinated, and now need decaffeinated.

So, to drink or not to drink, that is the question.
