活动海报角落写着「本活动最终解释权归本店所有」。法律上这句话？
A promo poster says “the shop reserves the right of final interpretation.” Legally, this clause is…?
全球翻车率（内测预估）
A有效，商家说了算
yǒu xiào，shāng jiā shuō le suàn · valid — the shop has the final say
B需要工商部门认定后才无效
xū yào gōng shāng bù mén rèn dìng hòu cái wú xiào · void only after a regulator says so
✓无效——商家不能靠这句话单方定输赢
wú xiào——shāng jiā bù néng kào zhè jù huà dān fāng dìng shū yíng · void — a shop can't decide the outcome by itself
D只在有争议时有效
zhī zài yǒu zhēng yì shí yǒu xiào · only valid if there's a dispute
「最终解释权归本店所有」是全中国最理直气壮的一句废话——它写在海报上，也写在无效条款名单里。
“We reserve the right of final interpretation” is China's most confident piece of nonsense: printed on posters, and listed among clauses that carry no legal force.
