Working in fast food it's common in the drive thru that the order isn't ready and you'll have to get them to park and bring the order out later because of strict timer goals.

Where I work we get them to park in front of the store. Usually they don't bother turning their cars around, so they're facing away from the front door. This means that when you come up to the car to hand them their food, you're walking up behind them which gives a great opportunity for downblouse since they're sitting down and they usually don't notice you right away either so it's easy to get a good view for a couple seconds.

It's the only redeeming part of having to work in the summer heat, usually the girls have more revealing clothes on. Going braless isn't very common in my country unfortunately, so I have never seen anything besides a lot of cleavage.
