The casinos' rules, and the souvenir street markup

You must be 21 to enter a casino, and photography inside is banned; dress is casual but no flip-flops in the formal rooms. Don't leave anything on a table if you don't mean to bet it. The almond cookies and jerky sold along the street to St. Paul's are cheaper in the shops a block away, and the free samples are meant to draw you in. Pedestrian crossings are respected; the stone-paved old town is slippery in rain.
