You can also go to an car dealership and work a deal to "test drive" one of their vehicles overnight with no intention on buying it, just simply to drive to a party to try to impress people and then take it back the next day and say it wasn't quite what you were looking for
.
I once worked with a not so moral person who pulled this stunt, just because you can doesn't mean it's right.
You can also buy clothes from a retail store, wear them to the big Christmas party and then return them the next day because "they didn't fit right", this should be acceptable practice too, as long as you are gaining and somebody else is losing it should be perfectly fine right?
