I want to use litecoin and byteball for my family bakery. What is the easiest way to get non-tech savy people set up with a wallet? [5]

We have a small woodfired bakery in the east of the netherlands with about 120 people who support us by buying bread. Mostly >40 years old, into organic and local. I think most people have computers and smart phones (probably mostly androids), a few definitely don't have either, most of them are not "tech savy". We bake for about 80 households, six small shops and two restaurants by order every week. I was thinking of using Litecoin with the Jaxx wallet. Since we can afford it for three months, I was thinking of only accepting cash and crypto. I was thinking of selling them bytecoin and litecoin directly along with their bread in €20 incriments. Then they pay for their bread in crypto a month at a time. <Profit> I could write a small article with some pictures of us showing people how to download wallets onto their phones with some bread in the back ground. Of course I wouldn't write it high. I digress.. This would be cool for the bakery but also for all of our customers, essentially giving them free bread (if they use Byteball) and introduce them to the Internet of Money. I thought about all of this while on my stoned run this evening. What do you all think? hahaha may Humanity prevail! Edit: I do need to get my wife to OK this, which means i first have to get her to set up wallets.
