没预约。但要等位。看在那儿等位时发生的真笑话：

前台：Please leave your phone # and we will call you when it's your turn.
我： But we're from Canada.
前台：(after discussed with a co-worker) We can call Canadian numbers, too.
我：But we don't have a cell (实话，我们一直抵抗手机，在两周后才拿到了人生的第一个）
前台：Oh, Canadians don't have cell phones. Then please wait here. 

我没忍住开始大笑，最后把肚子都笑痛了（也更饥饿了）。还好，没等多久就进去了。
