Wayback Burgers is celebrating the first official day of summer with free shakes on Friday, June 21st, 2019.
No purchase is required.
The free shake will be a 12 oz. Black & White Milkshake.
One per person. In-restaurant only, while supplies last.
The Black & White Milkshake is crafted with Blue Bunny vanilla ice cream, Hershey’s Chocolate syrup, Monin French Vanilla syrup and milk.
Last year, Wayback Burgers gave away over 34,000 free shakes. This year, Wayback’s goal is to give away 50,000 free milkshakes.
This will take an estimated 5,000 gallons of vanilla ice cream, 500 gallons of Hershey’s chocolate syrup, 500 gallons of Monin French Vanilla syrup and 50,000 cups lids and straws – 50 times the required supply for an average day of milkshake sales.
The average Wayback Burgers restaurant will give out more than 370 free milkshakes on Free Shake Day.
