下班了,怎么和老外打招呼?

很多阿

Have a nice evening! See you tomorrow!

如果是周五下班，可以说

Have a good weekend!

bye
see you
see you tomorrow
take care
have a good one
have a nice weekend
enjoy your weekend
enjoy the holiday
Happy mother's day

See you.
See you tomorrow.(明天见)
Bye.
Bye-bye!
Goodbye.

See you
bye
have a good time
see you tomorrow and so on

Hey, I'm off. See you tomorrow. (cool一点的回答: Catch u tomolo)
