If upset as a consumer, then maybe the store will refund your purchase price or allow you to exchange for another brand.
In my view, if the carton producer & egg supplier want to say “Have a good day” to me, I’ll respect their right to do so & I will deal with it. But, I don’t have to. Consumers have a choice.
Certainly there are issues which I would prefer not appear on my egg carton, but wishing me well & throwing compliments my way are not among those issues. As I wrote earlier, if you want to wish me well and encourage me to be positive & appreciative, I can take it !
P.S. Yes, I do understand & respect your position @abasket, but I also respect freedom of speech whether I agree or disagree. Moreover, I am not offended by the packaging of the positive message in a biblical quotation.
Also @abasket, I think you raise a clever issue: What if the message had been printed on the outside of the carton instead of on the inside ?
