Congratulations on your new job. I know you worked hard for it, cheers.
Cheers, it has been a pleasure working with you all these years. I'll make sure to come back and visit next month.
You'd better. Work won't be the same without you. So when do you start?
I went in today to fill out some paperwork but I won't start until the following Monday.
That's great, let me pay for your lunch. It's my turn anyway.
No, it's alright. I owe you for everything you have done for me.
Thanks, so I'll see you tomorrow then.
Of course, bye.
