You have to understand what blockchain is. It's not like a share that you can distribute to your investors base on what you have said. It's where bitcoin and any other coin runs. It's the network for most cryptocurrencies so it's not like an asset or dividend that you can give to those people that's longing to invest or buy a share with what you're trying to discuss here. As I have said, as long as there is no business model and profitable service or product you'll going to offer, it's more of a charity.
Actually tokens in a blockchain is a good way of determining the share of a person. You just need to look at the blockchain and you can see the addresses that owns the token and it is quite easy to distribute profits to the holder.
OP is having a different thought with that. If you have to back read, you will understand why I'm explaining it like that.
If you are providing free meals then how is it a business? Also as far as I know you can only do ICO with regulated investors in America. Since your token isn't providing any utility to holders, it might as well be classified as security and you might have difficult time going around it.
I think OP has work around on this "free meal". As stated earlier, this can be a form of promo, wherein every x purchase of foods a y number of a free meal is allocated. It not that hard to maintain this while profiting from a business. Though I agree that if their token is classified as security then it will need legal documents to proceeds.
There's no profit in this kind of business.
