Do you acknowledge the cash/check and show your spouse? Spouse (me) only notices that you are waving the card and does not notice the cash/check.

Do you not look at the amount and tuck it away for later to see what was given. Focus on the gift not on the amount...

Maybe I'm weird about getting money but I think it's something you look at more closely at later time in private... Counting money and examining a check while people are watching sounds so weird to me.
