You can use the Casserole Pan Set and Bamboo Appetizer Set for gifts, office party drawings, etc. Who isn't in search of (LOL) a misplaced flashlight now and then, so maybe not so bad. Backpack Cooler, again maybe for a hostess gift for some occasion, pool party, etc.
Designate a 'corner' in a closet for 'useless casino swag that might serve a gift purpose. Easier to look through one place instead of trying to remember 'where I put that thing I got from XYZ casino two years ago.'
But, are they worth using up a vacation day or half your paycheck for? Not usually, 'cause you can buy the same thing for much less than what you'd spend chasing it at a casino. JMHO.
