Surprisingly, no. I live in a college town and the majority of the store's clientele is Tucker Max wannabes or people driving up from dry counties. There's a few good stories though, such as this one.
Strangely enough, I find methheads and alcoholics quite boring in real life without any crazy dialogue. They just shake a lot or buy a lot of booze. Most of the people who want to start a conversation are middle aged or old people who have been buying booze routinely for years.
