Kandy handicraft stall quoted a high price then looked offended when I hesitated — how do I bargain without being rude?

Polite bargaining here is calm, brief, and face-saving. Smile, thank them, offer a lower number once if you still want the piece, or say you will look around and walk away without lecturing. Many stalls expect a little negotiation on crafts; some fixed-price co-ops do not — if a sign says fixed, respect it. Looking offended is sometimes theatre; do not match the heat. Walking away is not rude. Coming back with a final offer is fine. I will not invent a magical percentage off — know what the item is worth to you and stop there.
