You are fine

“I’m fine,” you answer carefully, “but thanks for asking.”

“No problem,” the guy says friendly, “if you need anything, just let me know.”

“Thanks,” you say and continue searching the store. You see several things you could need. A roll of thin but firm rope for three dollars, a few sweets for two Dollars or a set of tools for lockpicking for seven Dollars. You learned lockpicking from a friend in your old home town. With these tools you could likely open even advanced locks.
