Standard modifiers in Toast: 'no onion,' 'sub fries,' 'rare/medium/well,' etc. Non-standard requests: '86 the cilantro' (notes field), 'allergic to dairy — confirm no butter.' Allergy notes are always confirmed with the kitchen verbally, not just the ticket. Modifier abuse (e.g., a guest substituting 4 items): server has discretion to charge upcharge, with MOD review.
