Tropical Smoothie Cafe is hosting its annual National Flip Flop Day on Friday, June 5. Through this initiative, the brand will offer customers who arrive at participating locations wearing flip-flops between 2:00 and 7:00 p.m. a free 12-ounce Mango Monsoon Smoothie.
A permanent menu item, the Mango Monsoon Smoothie combines mango, pineapple, papaya, guava, passionfruit, and coconut. As such, the beverage is sure to provide a refreshing indulgence.
By drawing inspiration from National Flip Flop Day, Tropical Smoothie Cafe uses a playful dress code requirement to drive foot traffic and create a festive atmosphere. In addition to the free smoothie, scanning a QR code at the counter enters guests into a sweepstakes for a chance to win free smoothies for an entire year.
