Wireless haircuts

I've recently convinced my barbers to offer free wifi,  because when I'm sat waiting for my few remaining strands to be trimmed it would be nice to browse, slightly selfish I suppose. It was already inplace and he was paying for it, so why not offer it to his customers, so my wait is a little more bearable during busy periods. 
Originally he had concerns of people downloading big stuff or hacking etc.  I said if you change your password regularly, you know your customers as they need to ask for the password, so I would be amazed if anyone sat waiting for a haircut could do any damage in 5 to 10 minutes.
I'm quite chuffed with myself on converting my local barbers. I can google to my hearts content.
