Good! I hope it frustrates them right out of business. I would take my employee escort on one long and merry trip around the store.
It says that an unvaxed can only use the pharmacy with an escort and then the escort throws you out.
I would first head for the toilet.
Let the escort stand outside the stall, inhaling the fumes and listening to the "sound effects," for about 15 minutes, before actually looking for any items.
Regards,
