Let's hear your opinion about this.
Say you're checking out somewhere and the cashier asks if you want to buy this or that or donate to a particular cause. You say, "That's okay, thanks."
What did you just mean?
1. That's okay, you would love to donate/buy stuff. (Yes!)
2. That's okay, you do not want to donate/buy stuff today. (In other words, no. But you want to be polite and not say that word.)
3. It's okay that you are holding this promotion. Thanks for doing that! (Haven't answered your question yet, but I'm making chit-chat.)
And in your comment, let me know where you grew up and if this is a saying you've ever used. I'm curious! Thanks! :)
