What is the ruling on not alerting a seller who cuts mortadella for his customers and throws away the wrapper containing the name of Allah into the trash, given the frequent occurrence of this in malls and the embarrassment associated with giving such an alert?

"Allah does not burden a soul beyond its capacity," and hardship is removed in Sharia. So, if a woman sees a worker doing that in the mall, advising him is obligatory. It is preferable for her to ask her husband to undertake this advice, and there is nothing more required of her than that.
