一、美国的"隐形税" 如果你去餐厅用餐、打车、理发，可能会感到更困惑了。因为在美国这片标榜自由与平等的土地上，有一种近乎"隐形税"的文化现象，成为游客的困惑、 居民的负担，甚至引发服务者与消费者之间微妙的紧张。 这便是美国独特的小费文化。 二、我的四次不愉悦的支付小费经历 美国的小费文化，尤其是后疫情时代，发展得越发畸形，越像是强制性的隐形税。我有四次让我非常不愉悦的支付小费经历。 第一次是在纽约一家时代广场的餐馆吃晚餐，饥肠辘辘，落座良久，我们桌的服务生——一位年轻的黑人小哥——却如同消失了一般。四五次的招手示 意，换来的是一句句"马上来！"但没来。为什么不离开换家餐厅，因为那个时间点哪个餐厅都需要排很久的队，我们以为等再久也很快就可以上餐了。 在我们用餐的时候，他中途来问候，问过我们是否需要什么东西，我们说没有，接着他又来了一句突兀的自白："我从中午到现在都没吃东西，快饿死 了！你们的食物看上去很好吃" 。 作者供图 如果你是初来美国的游客，会发现结账时小票上的费用和商品标价不一样，因为购买商品（生鲜除外）需要加消费税。你可能会感到不习惯，因为你默认 在国内的消费就是最终金额，接受就支付，不接受就走人。但 ...
