Mary said she's had to take a rain check on my movie invitation.
I can't make it to dinner tonight. Can I take a rain check?
I have an important appointment with our customer tonight. can I take a rain check?
I guess I'll have to take a rain check on that.
Thanks for the invitation but I'll have to take a rain check this time; how about next week?
I was planning to ask you in for a brandy, but if you want to take a rain check, that's fine.
