I'll be happy to provide you with an example or two. The First Purchase Church serves to contrast the two different types of people who use the building. A place of worship for Maycomb's Negroes on Sundays, it functions quite differently when "white men gambled in it on weekdays." (Chapter 12) While the black parishioners give the building and grounds the reverence it deserves on the Sabbath, the white gamblers show no such respect. Although Scout calls the adjoining graveyard "a happy cemetery," she does not seem to understand about the "brightly colored glass and broken Coca-Cola bottles" that litter the tombstones. Scout sees the glass as pretty and colorful, but it is apparent that the white gamblers who use the property also utilize the grave stones for target practice with the bottles--probably both cola and whiskey--they empty each day. The church is a sacred place on Sundays but is used for sacrilegious activities the rest of the week, illustrating the intolerance that the white people displayed for their black brethren.
Like many "watering holes" during the Depression, the Dew-Drop Inn and Fishing Camp is considered the "county's riverside gambling hell." (Chapter 1) No self-respecting Maycomb citizen would think of paying it a visit; only ne'er-do-wells and residents of Old Sarum, like the Cunninghams, patronized it. (The old TV show, The Waltons, also set during the early 1930s, paid tribute to TKAM by naming their own decadent local saloon The Dew Drop Inn). Like Maycomb's downtown O. K. Cafe, "a dim organization on the north side of the square" (Chapter 11) which Mrs. Dubose uses as a threat to "terrify" Scout, the Dew-Drop is a place which proper citizens like the Finches try to avoid.
