Gushi 故事

At the ticket window, a small person keeps tapping the towering man in front to urge him to hurry up.

Transitive verb: 催 + person means "to hurry/press someone to act", e.g. 妈妈催我起床 (māma cuī wǒ qǐchuáng) - "Mom is hurrying me to get up".
Different from 劝 quàn "to advise/persuade" - 催 is about speed/urgency (get moving now), while 劝 is about changing someone's mind or decision.
催促 cuīcù is the more formal synonym pairing, used the same way but slightly more written.
催眠 cuīmián "hypnosis" is a fixed compound (literally "to urge sleep") worth knowing separately.
