Quebert,
I'm going to tell you all the negative aspects I'm thinking about, because you obviously already thought about all the positive ones. Also because I opened restaurants before, and because I miss making pizza now that I don't run a restaurant anymore so I'm also thinking about things I could make to give myself a win-win situation.
My negative points may be influenced by the Chinese market in which I am (and by the French culture also maybe), so just make your own filter and take what you want to take!
About the friends:
- some friends always tell you "you should open your pizza place, I'll be your first customer!!". Indeed they are, but they sometimes don't come anymore.
- some friends are not friends anymore once they pay. As Pizza_Not_War mentioned above... (cold pizza etc)
- as we say in French, "the advisors are not the purchasers".
- of course you'll have loyal friends, and customers who will become new friends. A kind of equilibrium, if you will!
About the safety (& regulations):
- Jack already mentioned it (gas etc), I didn't even think about it.
About the work:
- I think you'll enjoy it the 1st couple of months
- but think about the big disadvantage of the restaurant business: you don't have a family life. You work when your friends go to the bars, to the restaurants; when your kids go to sleep...
- I understand you want to play it soft (10 pizzas a day), but this may lead to 2 other problems:
- when you'll be ready to do more you will, so 15 pizzas/day then 20, then... until you have to open all day long. But you will not want it, so you'll make more pizza while keeping your 3H-window and you'll be tired.
- you'll have more and more customers, and if they're often refused they can be angry, you may lose them (maybe people will understand and pass the command in advance as you plan, I don't know)
- more pizza and more customers means more space and more equipment
So I think sooner or later there will be a line, keep the 10 pizzas/day or start a "real" business, and I will be harder to say "no" as you will already be "in", so you'd rather think about it now.
I know that you enjoy making pizza for your friends, I do, we all do here, but turning this into a business is another story.
But if it's your dream, I hope you'll make it, because even though I made a lot of mistakes when I open my own restaurant, and it was harder than I thought, I don't regret it!
