“So, I presume that there is a sign for all the Catholic cashiers,”
A Jewish cashier might opt out of pork. In fact, if we get ALL Wegmans’s employees to only deal with what they are allowed to or comfortable with, then everything would be fine!
Muslim, Jew, Catholic, Christian Scientist, LDS, Hindu, Sikh, and on and on.
So if a cashier happens to be a recovering alcoholic, will they post a sign asking customers NOT to buy beer or wine at his check out counter?
