I think the H&S thing is more about being sued, like schools closed when there is just a hint of snow, i also remember no Taxi would pick up children in care if there was ice around.
As for shopping, the internet is the best way for most products but not for some, I think the service shops, like dog grooming, phone mending, hairdressers, nail bars, tanning stations etc are doing well as are the cheap shops where postage would make the item too expensive.
A women I spoke to wanted to open a dog day care center in our town, she had the ideal building and all was agreed but the local council planning kept stopping her, now how bad is that? she now has one in Stirling and its doing great...I would love something like that and there is obviously a need, (sorry if Mr or Mrs planner for our area is on here but if they are I would love to know the reasons?)
We wanted to open a tea room but the planning was a bit too expensive and we gave up, then a take away little shop opened across from us and its doing very very well, we could kick ourself as the chap who owns it asked US if we wanted it and we said NO, also all the young people at the youth club also asked me to open it up...talk about missed opportunities.
Anyway, I think it must be hard to be truly self sufficient unless you have a fall back income, something like a skill you can sell......I am off now, as I am not clever with words, I know what I want to say but cannot seem to make any sense, things move on and change and that's how it goes, anyone with forward thinking ideas needs to grasp them and get them up and running.....seize the day!!
