High Temperatures Spur Ice Cream Sales
Although rising summer temperatures typically mean high electricity costs for the average homeowner, this month’s heat wave is having an unexpected consequence: a surge in attendance at local ice-cream parlors. According to reports from local business owners, industry sales have increased as much as 50 percent compared with the same period last year. While this recent boom might have been expected to produce a rise in the price of products like milkshakes, prices in the downtown area have remained steady. Other retailers benefiting from the sweltering weather are those selling soft drinks and appliances, such as air conditioners.
