In a typical Indian home, if a guest arrives unannounced at meal time, they do not apologize. They are fed first. The host will starve before allowing a visitor to leave with an empty stomach. This extends to modern lifestyle habits: the insistence on "tucking in" a friend with multiple cups of chai, the refusal to let anyone leave without stuffing a bag with mithai (sweets), and the absolute horror at the idea of "splitting the bill."
