MANNER
Do I meet all customers without reference to age, sex, or dress, as if I were genuinely glad to see them and sincerely interested in serving them intelligently and well?
Am I businesslike without being brusque? dignified without being stiff? unvaryingly polite but never oily or servile?
Do I treat all customers with real courtesy, and none with cheap or offensive familiarity?
Do I ever permit myself to look or act bored, tired, indifferent, or sullen?
LANGUAGE
Is my voice pleasant?
Do I talk enough, or too much?
Do I talk carefully and well, without grammatical blunders or slang, and with an adequate command of words, or do I stumble, use poorly chosen words, and repeat myself until my customers are bored or repelled?
