Hello. I wrote two dialogues. Will you check these?
No. 1 (M is a police officer.)
M: You realize you were going sixty in a 30 mile-an-hour zone.
F: Never, officer! I had no idea I was going that

fast.
M: Please check your speedometer from time to time while driving.
No. 2
M: I'm supposed to [will] have a job interview with Ms. Brown.
F: Oh, you must be Mr. Shults. Please be seated [take / have a seat].
I'll let her know you are here [came here].
M: Thank you. And would you tell me where the [your] restroom is?
Thank you!
