The screens are there to play ads sometimes, and if you get there while an ad is playing, you either have to know the store and remember which screen the thing you want is behind, or you have to wait until the ad is over. Or you can go open every door until you find what you want. I prefer the latter because it makes the company have to pay more to cool their drinks.
If enough people do it enough, maybe it’ll negate the advertising profits.
