Same here. In my opinion, I doubt most PCs know how to count, so I ignore it when they start sifting through the discards, BUT I do plan a very quick and swift exit shortly afterwards. They're most likely trying to test your reaction though, so it's probably best you don't leave the table immediately. I would play out a few more rounds or another shoe if it's a DD game, then casually leave after that.
