hang on

Hang on a moment; I need to check whether the pharmacy is still open.

等一下，我得确认药店是不是还开着。

And then coming up with a mechanism of being able to say, hey, hang on, this doesn't look quite right.

然后想出一种机制，能够说：嘿，等一下，这看起来不太对。

Hang on while I find the confirmation email, and then I'll tell you the booking number.

等我找一下确认邮件，找到后就把预订号码告诉你。
