The snack vending
Snack – the light meal, at us is the packed up goods for fast "having a snack" (even faster, than fast food): chips, chocolate, cookies, nutlets... etc.
Snek vending machines – automatic machines for snack sale, but in Russia often are understood as automatic machines with spirals for goods delivery. At rotation of a spiral it submits the goods forward. Spiral delivery - the cheapest, but not the most reliable.
