@Zweiblumen: Your post is great. No need for corrections.
@Malevolence: The man is suspicious (-1) but Ohanzee wants to spend money which is advantageous to the salesman (+1). Those offset, so he'll roll to resist 3 hits.
Perception + Charisma:
5d6t5 4 hits, goodness, he is the suspicious type. He is now Prejudiced instead of Suspicious.
@Mal, you can roll your Con story if you want to try and improve his attitude, or you can just grin and bear it.
@Everyone: I'm not sure I have a complete shopping list. Chime in if we're missing anything:
Ace: helmet (¥100) or ballistic mask (¥150) + SecureTech PPP (¥900 for a full set)
Doc: helmet or ballistic mask (same as above)
Chino: armor
Sam: armor (optional) with chemical protection (Doc/Katsina's solution of BoPEP blanket sewed into his clothing protects Sam's armor, but inhibits stealth)
Ballpark is ¥2,000, presuming you don't buy anything for Sam. You have enough to afford two extra sets of PPP if you want, with enough leftover to buy groceries for another day, but then you'll be broke after that.
