Boycott
"To engage in a concerted refusal to have dealings with (a person, a store, an organisation, etc.) usually to express disapproval or to force acceptance of certain conditions."
"No! I will not stand for this!" Erza slammed her fist on the bar for effect. "How dare they think they can get away with this!"
Mira smiled tiredly at her distraught girlfriend, mindlessly polishing the glassware around her. "Well, it has been on the menu since he first opened," she offered, trying to calm the Requip mage down and help her see reason.
"That's the point!" Erza said. The other mages at the bar had all scurried away, other than Lucy who was too busy with her nose in a book. Mira supposed the guild was quiet compared her life at home now, so it was no surprise that she wasn't really paying much attention to Erza's dramatics. That, and she was probably used to it anyway. "It's a classic. His entire business was built on that cake!"
"I'm sure he'll add another one to the menu in time," Mira said. "A better one, even."
Erza shook her head, mouth agape at what her girlfriend had just suggested. "Preposterous! Nothing could ever top the classic strawberry sponge. In fact, I think we should all stop going there until the owner brings the original menu back." Erza looked to the blonde beside her. "Don't you agree, Lucy?"
Lucy looked up from her book, looking around dimly. "Hm? What?"
"Boycotting the bakehouse."
"Oh, yeah, sure…" Lucy murmured. She didn't know if it was worth mentioning that she'd never actually been to Erza's favourite bakery.
"Excellent. I shall alert everyone else in the guild of this boycott at once."
Mira could only sigh once more as Erza rose from her stool to do exactly what she said.
