Is the unwritten stay out of your wife's purse/husband's wallet practice a uniquely American thing?

If I'm in another room and ask my husband to get something from my purse, he brings me the purse so I can go in and get whatever I need myself. Likewise, if he tells me to get something out of his wallet, I take it to him and let him go in for it.

This is common where I live, and with the people I know.

What about other countries beside the US, or US regions besides the Midwest, is this common practice?

I already know there will be several comments about women's purses containing a lot of clutter, and even kitchen sinks. You're free, of course, to make them, but I'm more interested in answers to the question.
