I once worked in a service station. A truck driver came in and bought some porn and a windscreen wiper blade. He started to whack the magazine with the wiper blade saying “I cannot wait to beat the girls in here.”
When he walked out, I put a sign on the magazine rack…Porn not for sale this shift, due to night managers Christian beliefs. Do not ask as refusal may offend!”
It did offend, and one time one guy asked two coppers who came in for coffee to force me to sell it.
Did I do the right thing or not? My conscience tells me I did. The boss told me he couldn’t sack me over it..but nor could he allow me to not sell it as it made him a lot of money. (He also said he was a Christian, but you have your christian life, home life and business life. ) I said that is easily fixed…I left.
