How much should I tip for takeout or counter pickup?
Tipping on takeout is 100% optional (0% is standard). Leaving $1–$2 or 5%–10% is generous for large or custom orders, but never mandatory.
What should I do if the receipt prompts 25% or 30%?
Standard restaurant tipping in 2026 remains 18%–20% for good service. High default prompts (25%–30%) are merchant marketing defaults, not required etiquette.
