If politeness counts, then the (older) lady who ever-so-quickly collected the balance of my payment (for my custom picture frame) needs to learn some manners; at her age, she should realize that it's impolite to rush a new (now former) customer's payment while he's still perusing the nicely finished product. It was needlessly crude behavior, as subtle as it was. The other gentlemen however were more polite; still, this minor (to them) experience has never the less cost them one customer with considerably more business which will be taken elsewhere.
