Why Throwing Milkshakes and Eggs Has Become the Perfect Act of Protest | Eater

"A branch of a global fast-food chain in Edinburgh was reportedly asked by police not to sell milkshakes during a high-profile politician's visit, illustrating how the drink's recent use as a protest projectile has made such outlets inadvertent flashpoints. The request underscored growing suspicion around patrons carrying shakes and even contributed to a visiting politician's decision to remain on his bus rather than disembark after seeing people holding milkshakes. The episode shows how retailers may need to change sales practices and increase staff vigilance during politically sensitive events." - Jenny G. Zhang
