So, my experience has been that in Starbucks in the USA (Seattle) you can jack in power and nobody says a word. Especially if you're ordering drinks etc. Trying doing that in Thailand and you get a completely different attitude. (They are worried about the power charge here. Not worried so much as see it as something that should require payment before use.) ... So it's not all that Laptop friendly if you don't carry spare batteries with you. I'm curious to know what it's like in the UK. A british friend of mine once told me he was accused of "stealing electricity" when he plugged in his laptop in a Cafe around Manchester. I'd expect similar treatment in other parts of the country too. Here in Bangkok, Thailand they offer free wireless internet in Siam Discovery as a promotion from Copperwired (Applecenter) and another company. Anyway, whilst the service is pretty slow it works but the management at that complex strictly forbid customers plugging into the vastly available power sockets used when vacumming the floors. ...
