Look bro, ive done the restaurant gig. If you don't mind getting calls from your 18 year old assistant mgr at 1am crying cause his cash drawer is short $15.00 and it's going to be a mess in the morning because little susie had her period and had to leave early, go for it.
This is not hand them 50k, show up once a week, and rake in profits. You will be there often, you will make sandwiches, you will live, eat, sleep, and shit the business.
If you like your free time, dont do it. If you want something to occupy all your time, go for it. Go ahead and think youll just hire the right people, cause no one will do it the way you like.
And besides, your fat ass will probably just eat all the profits anyways!
BTW--don't mean to change your mind with all the negativity, you just need to be aware of what your getting into.
