I am in OH also. I have been doing this for 7 years.
I have people come pick up their orders at my house all the time. It has NEVER been a problem.
No one has ever just showed up looking for cake or a consultation. I have had people call asking where exactly my store was so they could stop by and pick up some cupcakes or a last minute cake but I just explain that I operate out of the kitchen in my home, am a licensed home bakery and that I only make custom orders. I don't have anything just lying around for them to pick-up. They always just say "ok, thanks." No one has ever actually come to the door or anything.
It is much easier for me to have people come get their order from my house rather than make arrangements to meet them, leave my house with the cake, meet them somewhere else, and then have to come back home again. Usually I would have to take my kids with me. Unless it's a tiered cake they can come and get it. Or they pay for delivery.
I set up an 1/2 hour to hour window for them to pick up and tell them I have to leave shortly after. I make it very clear that if they aren't here during that time they won't be able to get their cake. I've never had anyone late OR they make sure they call and tell me they are on the way so that I don't leave the house.
Honestly, if someone wants to find out where you live, in this day and age of internet info it's incredibly easy to do so, no matter how guarded you are with your information.
