Re: Long way around the barn!
I've spent the last 10 days with a my Boots Advantage card in the power slot of my Hamburg apartment
Being an EE by trade I figured that one out almost immediately on a business trip in the Netherlands. As soon as I felt the telltale single "mush" of a basic pair of contacts, in went the first convenience card I found (to shops they didn't have of course, so relatively useless). No more worrying about phones not charging, laptop dying etc. for the rest of the stay.
I get power is expensive, but will the hotel be paying for my overpriced standard fare after my phone dies due to not charging? Or for lost contracts after I don't meet with the clients I'm there to talk with? Didn't think so.
