That's pretty heinous of Frita. You should know well not to mix businesses with their rivalries. For a future reference, never:
1. Mix Coke with Pepsi
2. Use a Target gift card at Wal-Mart
3. Order a Big Mac at Burger King or a Whopper at McDonald's.
4. Play a Nintendo game on a Sony device and vice versa.
5. Replace Windows 7 with iOS 8.0 on your computer.
6. Search Google on Yahoo.
7. Or wear two shoes, one of each from two rival companies
