It's easy for me to point out these things though, people often have some thing they think they should've brought up when they had the chance. I used to do telemarketer work, and the only plus side to having the same kind of conversation again and again is having the chance to use the rebuttal at a later time.

You are in the same kind of situation, so I'm sure you are aware of that kind of perk as well.

You do a good job, keep it up.
