Tips & ZIPs
When a ZIP code is required, why is the city and state also? What if they disagree? It there is a tiebreaker field, then only that field would matter. If it's for smudges or legibility, then have me write the ZIP twice, just as one might verify an email address. I understand that ZIP codes are not geographical spaces, but sets of mail routes that resemble polygons, so maybe the reason lies in that twist.
Similarly, why ask for a tip amount and the total bill amount? I saw a friend once write in a total amount, then put "math" in the tip line. Even better, why not just ask me what % or $ to leave. This would be easier, but maybe the register software isn't yet capable.
