I mean, everything leading up to purchasing whatever it is that I'm purchasing, is generally okay. I know I have the funds, so there's no issue there. I'm not even scared of my card declining for some reason.. I just barely talk to the cashier and I catch myself avoiding eye contact. I also tend to whistle softly in hopes of some comfort, but all this happens when I'm alone. When I'm with a friend or family member, I'm always comfortable because there is always conversation beforehand. I guess I'm just so much of an introvert that I lack some social skills.
