客

1. Origins, structure, and basic meaning

• Structure: 客 (きゃく) can mean a shop customer or transport passenger.
• Basic usage: Two customers are already in a shop; a station attendant guides a passenger unsure about transfer.

2. Common pitfalls and similar expressions

• Customer in a store and passenger in a station
  • Setting 店 selects customer; station and transfer context selects passenger. Do not fix one English gloss for every visitor.
