Cash costs more nearly that much when you count all the time spent counting and recounting it - at least 8 times for every transaction. (the buyer finds and counts, then the cashier counts, then count change. Then the manager counts and recounts the till, finally the bank counts and recounts it - several of the above will come up with a miscount and recount additional times to verify). Then we add crime loss on top of that.
