Hi clo,
Did you sue them?
If you didn't, I'm with you.
People have different ideas of right and wrong. These sometimes lead to conflict.
It's annoying when someone else's ideas of morality are in your way, but it's the sort of thing there is freedom of choice for. Pharmacies operate in competition in most towns. Why not move your custom to another store?
This isn't the same situation as hospitals which are often monopolistic in providing their services over large areas.
