It's my treat !!!

Stanley	You look tired. Would you like to have a cup of coffee with me ? It's my treat.
Nancy	OK. Caffeine is exactly what I need right now.
Stanley	How is every thing going ?
Nancy	As usual, I keep visiting clients, working on proposals and making phone calls.
Stanley	Yes. I am glad to see that you hold on to these routines. Most the people think that the work can be tiresome and they started to lose interest.
Nancy	I agree. Sometimes the clients' refusals cause me great distress and I found it difficult to deal with it.
Stanley	I can totally understand. Still, I hope you can keep up the good work. Where there's a will, there's a way.
