We bought a small coffee pot yesterday.
We ran the numbers on buying our morning coffee every day from a cafe or from Starbucks and realized that for a couple of Euros more, we could get the pot and the freedom to have our coffee the instant we wake up. So for 22 Euros, we gained a lot of flexibility.
Of course we can't bring it home, so the cleaning folks will have a practically new pot if they want it. And we will have had our coffee first thing in the morning, which will really count on Friday. Our flight leaves Barcelona at 6:30 AM and I can promise you, no store will be open two hours prior to that. This is Europe, after all.
Have you ever bought something like that on vacation, something you know you can't take home with you?
