In the early 1980’s at a very popular restaurant a high level Cocoa Cola executive ordered a coke with his lunch. He was served a Pepsi, this was a fountain soda so there was no can or bottle and the exec noticed the difference and made a really big stink to the management. Shortly thereafter, the restaurant had all their menus, drink napkins and coasters reprinted to say “WE DO NOT SERVE COCOA COLA PRODUCTS”
Quite a few years back, the wife of an employee at a Coke bottler brought him lunch from a fast food restaurant that served just Pepsi.
A Coke senior manager was also in the lunch room and told the employee he could not drink the Pepsi unless he went off property.
The employee refused, drank the Pepsi inside the Coke lunch room, and they fired him.
The case went on for years in court, and last time I heard all the judges involved had upheld the original firing.
The fired employee claimed the judges were biased Coke drinkers!
