I agree, cash is king.
But if a friend, one you knew was not a deadbeat, wanted you to accept a post-dated check for a pin, would you even consider it?
Remember checks? They still work, and it's still illegal to pass bad ones.
What other details in such a scenario would make it work for you, or not? Local? Length of post-date? A couple hundred extra simoleons?
Is the post-date the deal breaker for you, or would you not take a check no matter what? (I realize banks say post-dating at all is a no-no, but how would they know unless you deposited it before the post-date? And that would be asking for trouble.)
A lot of stores have even stopped accepting them. But a friend is different, or is it?
