Should I ask my manager and owner to remove the beer boxes, even though it may upset them?

I?m a Muslim working in a gas station in Calif. USA. My manager and the owner are good Muslims. Both helped me a lot when I first came to this country a year ago. We don’t sell any liqueur or lottery. The mother company keeps pushing the owner to sell liqueur or he would loose the store. Today; the manager bought a few beer boxes and put them on the shelf at more expensive price than the liqueur store next door so nobody would buy them. He told me we have to do it till we pass the inspection by the mother company. I?m afraid if I ask them to leave they would get upset. They would think that I?m showing off that I?m more religious than them because they already told me we won’t sell them. Also; it’s not easy to find a job nowadays especially with good people like them. What should I do? Please answer me as soon as possible.
