There will be restaurants and flights that only take the unvaxxed as their customers. Capitalism is awesome.
Logically speaking, no business will cater a "Unvaxxed Customers ONLY" as there is a huge gap between vaxxed to unvaxxed. If you do this, then there is a tendency that your business will be ruined not unless you overprice the products, or build your business in a unvaxxed concentrated location
The other side of that is, we will be starting all kinds of new businesses that will be for anti-vaxxers only. They don't want to get jabbed, but they also don't want to get contaminated by the vaxxed super-spreaders.
Anti-vaxxers are starting their own businesses and communities. It's just the beginning for them.
And as I've said, this kind of businesses tends to go down after they've been build due to the lack of potential customers, but if this anti-vax will settle down into one place and then build their own businesses and communities there, then its another story.
