Cheat Sheets at the table?

So I'm playing at one of the larger casinos in Colorado. While the dealer is shuffling, the player next to me pulls out his basic strategy chart and sneaks a peek. Dealer says to him, "no problem, you can keep it out while you play." The pit boss walked by, didn't say a word.

A couple of questions:

1) is allowing cheat sheets at the table "standard practice" in Vegas, Atlantic City, etc?
2) might it be a good strategy for an AP to put his cheat sheet on the table, as a decoy, to give the impression he is an amateur?

Other comments?
