I have run the concession stand for the past 2 years for our high school city sectional swim meets. I try to pick healthier foods, since it is the swimming world and most swimmers are fairly health conscious. The most popular items are hot pretzel w/ cheese, hot dogs, taco boats (chips, cheese, taco meat, lettuce, sour cream, jalapenos, etc) jumbo muffins (any time of day) (bannana nut, chocolate & blueberry) (Sam's Club muffins in their bakery freshly made in six packs). Banannas, YOGURTS!, bagged red and green grapes, Carrots & Dip and also Celery & PB are huge sellers. On a sweeter note, I also get parents to make baked goods like brownies, chocolate scotcheroos, and we cut them up and put them on a plate with a set of pinchers & small paper plates next to them and people help themselves....big seller because it is right in front of them "teasing" them. Fruit snacks, in small packs, are also a big seller. We sell them for .25 each because a lot of times kids only have a small amount of money and are looking for a snack that their last quarter will buy. Sour Punch Straws are, by far, our biggest "candy" seller. We sell them $1 each pack.
