It's the 21st century, fellas. I don't even go to the bank. Ever. All funds are direct deposited and I use a debit card for almost everything. Except: 1. If I'm buying a gun, I get cash. I don't want any bank problems gumming up the works. 2. If I'm going out to the bars. I don't trust myself on a tab. 3. I pay my roommate in cash because he doesn't need the money bad enough to bother going to the bank for sometimes 2+ weeks to deposit the check, and nothing bugs me more than waiting on a check to clear. 4. If I'm buying something from an individual, gun or otherwise. I have literally never ran into any other situation where cash was needed.
