How It Works

Time-of-day arrival curve produces more students around class transitions. Each arriving person is assigned a demographic, then rolls a purchase chance. If they buy, an item is sampled from that group’s weights. Service takes 40–110s depending on complexity. Revenue and unit costs accumulate; labor and fixed fees settle at close.
