I believe that you have run into difficulty with some person(s) not understanding that $2 bills are real money.

I don't believe that they've been anywhere nearly as much of "a pain to spend" for you as you're stating. You're just gabbing.

They're socially awkward to spend, because people don't want to take them. That was true each of the four or five times I used bills from my father's stash, though I was outright refused only once. Unlike my father, I don't enjoy needlessly provoking minor hostility, so I turned them into the bank. We're all just gabbing on the internet, my dude. You might find $2 bills a fun investment.
