Yikes! Such commotion here
For me, fee money is geat, but not at someone else's expense. If they can make the mistake of giving back too much, then they could also make the mistake of charging too much as well. No one would complain about the extra cash, but I'll bet you would complain 10 times over if you were charged more than you should be. Gotta think the whole thing through here. Honestly is the best policy no matter who you are or the situation at hand. In the long run you'd be best off telling these cashiers that they are horrible at their jobs and need to re-take math! lol Though accidents do happen, even to the best of us.
