> I asked a couple of waiters about them, and they had no idea what the dingbats were for. That tells me that they don't use them for anything. They use the barcodes for everything. That makes me wonder if the dingbats were put there for restaurants that didn't invest in the bar-code system, as some sort of alternative verification. Or maybe they're only used by auditors. Or in expense reimbursement.

I like the hash for audit theory.  It makes it harder to fake a receipt, 
which otherwise would be pretty easy if you're sending in scans of 
receipts, just load up gimp and cut and paste a few digits to adjust the 
amount.
