These are the bank "clients coming and going to leave their money or draw it out" that Flem watches in The Town (146). In class they range from the old county families with "ponderable deposits" in the bank (293) to "one-gallused share-croppers" whose typical net worth is a single bale of cotton (291).
The "teller" at the Bank of Jefferson assists Ike McCaslin and Lucas Beauchamp when Lucas collects his inheritance from Lucius Quintus Carothers McCaslin in Go Down, Moses (106).
In "Mule in the Yard" and again in The Town, the "teller" at the bank hands Mannie Hait her money when she cashes out her insurance settlement (253, 244). (There is also a "cashier" on hand at the time, so we create two characters - though usually the terms "teller" and "cashier" are synonymous.)
In Requiem for a Nun, Temple Drake's account of the confrontation between Nancy and the cashier mentions that "fifty people" were waiting to get into the bank when it happened (96).
In The Mansion, the presence in the Snopes bank of this "professional cashier" - "imported from Memphis" - is a sign of post-World War II progress, the "industrial renascence and rejuvenation" that has reached "even rural Mississippi banks" (400).
In Light in August, this cashier brings the sheriff the envelope that Joanna Burden deposited at the bank, addressed by her "To to be opened at my death" (294).
In "Dry September" this cashier is a "widower of about forty - a high-colored man, smelling always of the barber shop or of whisky" - who takes up with Minnie Cooper in "Dry September" (174). He owns "the first automobile" in Jefferson, in which he and Minnie take drives, scandalizing the town (174). About four years after their relationship begins, he moves to Memphis, where he works in another bank and, according to Jefferson gossip, is "prospering" (175).
In "That Evening Sun," Mr. Stovall, the cashier in the Jefferson bank and "a deacon in the Baptist church," knocks Nancy to the ground and "kicks her in the mouth" when she accuses him of having failed to pay her for sex (291). In Requem for a Nun, where Nancy reappears as a major character, Temple Drake re-tells this event; she does not name the man, but refers to him as a "pillar of the church" (96).
The bandits in "A Name for the City" and again in Requiem for a Nun are "a gang - three or four - of Natchez Trace bandits" captured in the woods and confined in the settlement jail just long enough to stage an escape that adds a kind of shine to their image (201, 4-5). Local rumor suggests they may be associated with such historically famous bandits as the Harpes or Mason or Murrell, but the narrator seems to believe they were simply part of the "fraternity of rapine" that was a common element on the frontier (201).
