Re: Reliable internet
I was looking at that and thinking "who doesn't have a smart phone for business?"
While it's entirely possible he's unable to connect his PC to the internet via tethering (your business means going to homes and you don't have a laptop?) it's almost unthinkable that he wouldn't have access to email. Even for the most basic of businesses there should be multiple ways to access emails. He certainly seemed able to get onto Twitter at least.
This to me just strikes me as someone who hasn't thought about any contingency planning and is trying to do everything with the bare minimum. Hopefully this will persuade him to actually consider how he runs his business.
(Edit - just looked at his Twitter feed and it would appear that he's a serial complainer with a huge sense of entitlement. Also, why are people still using gmail for their business emails?)
