I'm not sure it's quite that bad LOL, but for sure the court intended for a Christian to be able to turn down a job that he/she felt would be morally wrong, unethical etc. for him/her to do.
I wish they had gone further and said all customers should be entitled to buy whatever a proprietor has for sale but the proprietor has a constitutional right to accept or reject whatever jobs he/she is required to contribute to (via his/her expertise) or participate in that he/she chooses not to accept.
Stores tell me all the time that they don't carry this or that product, and many a contractor or service company has told me they don't have time to accept a job I I need done or can't do it for the price I can pay or they just aren't interested in the job. It never occurred to me that I was being discriminated against because they wouldn't accommodate whatever it was I was looking for.
And just like nobody should have to apply a label to not to eat the wrapper the food is sold in, nobody should have to advertise what products they will carry, what they don't carry, or specify what jobs they will do and what jobs they will not do. There are far too many products and circumstances to list them all.
