1. At the drive-thru teller NEVER get in line behind a minivan.
Anyone who drives a minivan is either handicapped, elderly, or a parent. In any case, when it comes to doing the bank thing they’re unprepared or just naturally slow. This is confirmed by significant anecdotal experience. Today I followed my own rule and did not get behind the minivan. I was able to see the driver from my adjacent lane once I made it to the front. She had her entire brood in tow including a dog or two. Meanwhile, she had a nice long conversation with the bank teller over the intercom about her kids and all that cute stuff.
