The Irrelevant Credit Card Slip II

This blog is written mostly tongue in cheek. Some points may be informative. Please provide your feedback.
If you suffer from self-irrelevancy, please seek professional advice.

Hello. Okay, so we give people the credit card slips so they have some confirmation they bought something.
But don't they have the actual item in their hands? And what about their monthly statement? Or the list of items we print out so they can find them on the auction tables? To me these things make the credit card slip irrelevant.
I mentioned these points to my spouse, who agreed with me.
So we both think the credit card slips are irrelevant.
Will we do them next year? You bet!
Why? Because rather than take a survey of our guests to see if they also think the slips are irrelevant, we'll assume they think they're relevant.

Regards,
Irrelevant
