A long time ago I worked at a startup company with a pretty decent percentage of smart people. Oddly, the company paid us on the final day of a two week pay period, instead of two weeks later, which was the standard at the time. That was weird because they had to get the paychecks ready before they actually knew if we had worked the whole two weeks.
At some point, the company wanted to switch from paying people on the final day of the same pay period to paying two weeks later. Management realized this would cause a two-week gap in peoples' cash flow, so they decided to extend everyone an interest-free loan in the amount of one paycheck, that they would receive when they would normally have received their paycheck on the day we'd be missing one. The loan wouldn't have to be paid back until the employee left the company. Sort of a replacement paycheck that you could keep until you left. Before the change, if someone left, they immediately stopped getting paid at the end of the current period. After the change, they'd still get one more paycheck after the current period ended.
So the company was basically making the change smooth and transparent to the employees while giving them a slightly nicely advantaged chunk of money to use at no cost for as long as they stayed employed there.
Whoa. You should have seen peoples' reactions. Several people just could not understand what was going on, and although this company treated us all very well (there were only seventeen of us and we all knew each other), they had a knee-jerk reaction of distrust. I remember sitting in a conference room with everyone, exasperated with how silly some people were being and trying to keep my mouth shut. Even after examples were laid out in front of them showing that "before" and "after" were equivalent, they insisted that the owner was trying to short them somehow. I was in my mid-20's. That was a big lesson for me in how arithmetic-challenged many people are.
