1) Smile. A belle always smiles prior to speaking her mind. It disarms the opponent (note: particularly effective if said opponent is of the male gender).

2) As soon as you've acquired full eye contact, still smiling, begin with a question. This puts the belle in a position of power.
Example: My, My! Are y'all always so busy?Perhaps I should come back another time?

3) When they begin to stammer an apology, smooth things.
Example: Well, that's all right dear. Size six in this style, please.

4) They should at this point be scampering off to do your bidding. If not, don't assume that they are insolent. Some folks are just a little slow (especially those without the benefit of a Southern upbringing), so step closer and repeat yourself slowly and clearly.
Example: "Size 6, please!" Remember to continue to smile sweetly.

5) In the highly, highly (very highly) unlikely event that the salesperson is still standing there like knot on a pine bough, simply give them the Southern belle stare down (eyes narrow, lips purse but continue to smile, arms fold, high heel foot taps preferably to the beat of the Confederate battle tune "Dixie").

6) They will at this point tear off in fear, possibly tripping over shoe displays. Do try not to laugh, as it's frightfully poor sportsmanship. Simply go and seat yourself in the very center of the establishment.

7) Do not remove your own shoe. Remember that you are being served here just as everywhere else in your realm. It's good form, however, to arch your foot delicately to assist in your own shoe's removal as well as to ease the soon to be acquired shoe on to your foot.

8) Pause demurely for the inevitable compliment on your finely pedicured toes, then ask the price while casting a slightly disparaging look at the shoe.
Example: "Well, it is a good color." (thoughtful pause) "Hmm. How much?"

9) Laugh with sincerity, offer a compliment to the salesperson sharply expressed wit, then repeat question.
"Now really darlin'. How much?" The price will have dropped by at least 10% at this point. The next steps will depend upon the salesperson's gender.

10) If opponent is female:
Rise and proceed to the cash register.

If opponent is male:
Flutter lashes and whisper, "Sir, surely you being the senior manager here, you could offer a tiny little ole discount? I was hoping to pay with cash..." While he is grinning and shrugging, push a $10.00 bill into his sweaty hand, then sweetly demand a receipt.
