WAFFLE HOUSE is typically a port in a storm. The breakfast restaurants are so unshakeable that the federal emergency-response agency uses their closure as an indicator of a severe natural disaster. Yet on February 3rd Waffle House wobbled—it announced a 50-cent surcharge per egg, citing rising costs due to avian flu. The shell-shock is widespread: the average cost of a dozen eggs is now over $7 (see chart), a 140% increase from a year ago. Even so, supermarkets are selling out.
