Ok Susie, as someone who has been there and done it - 2 years in a store and post office (I was sub-postmistress) we did papers, food, alcohol, ciggies and worked from early morning 6.30 ish to 9pm and then there was always paperwork to do afterwards, getting good reliable staff was horrendous, it was a 10 year plan and nearly split us up after 2 years so we sold it. You have to sacrifice a hell of a lot to run your own business, holidays being the first, we had to cancel one we sorely needed when the person who ran the shop while we were away fell ill the week before. That was the last straw after being targeted for being gay, (I know that would not affect you), shoplifted from (yes I know it happens everywhere but this was blatant), graffiti, previous owner having fiddled vat which impacted on us (and he was still our landlord which really rankled). Yes there were good points, good community spirit (only shop in the village) we increased turnover and profits despite never having done it before, sold it for a lot more than we bought it for.............but had no life.
If I had my chance again I would go for something with less hours, not open 7 days a week as we were (only Crimbo day off) and a cafe really appeals to me. Profits are much better on food too. Can I come and join you in the venture - 5 bedrooms is more than enough for 2. (not entirely joking here after today).
