Candid Camera is now Punk'd, I Guess

Yesterday I went to the bank, and I went through the drive-through lane. There were three lanes in total, and I went into the empty one. While I was waiting, the person in the far lane got the tube thingy back, and they proceeded to back out of the drive-through lane. Obviously there was no one behind them, but there also wasn't anything blocking their way forward. The person next to me had a small trailer behind their truck, and they also backed out of the drive-through lane. There was plenty of room for them to get through the front with the trailer. I was perplexed by this time, and I looked all around for hidden cameras, but saw none (that's why they're called hidden, I suppose). I resolved that I was not going to be one of those people who just blindly does what other people do before them, wrong or not, and left in a forward motion. Thankfully I did not explode or run over a bunch of glass or end up on Youtube, but it was strange nonetheless.
