Alex:
Warehouse Keeper Sonin, Grocer Pano, and myself all need help. If you assist me, I am willing to write you a letter of reference.
I am sure that Sonin and Pano will do likewise if you help them, too.
Ask about Warehouse Keeper Sonin's problem.
Ask about Grocer Pano's problem.
Ask about Alex's problem.
Let Alex know you understand the problems of the townspeople and are ready to begin helping now.
