Hobby Lobby Stores

So im in check out and im about to pay the girl I hand her an old $20 bill as policy they check the big bills under a light she had the bill double checked by 2 other workers before calling the manager up bec some green light wouldn't show up when she ran the bill I told her I got money from the atm and it gave me a bunch of old $20 bills. The manager came up checked it again under the machines light and askec me if I had another form of payment I said yes but I didn't want to use my card he said we cand except my $20. I was so pissed off I walked out without my items.
First of all my time was wasted having my $20 bill being passed around from worker to worker an not to mention the girl checking me out had asked for my other $20 bills that were also old I was so hesitant to give her. Secondly the manager didn't even bother to use a counterfeit pen on my bill which was stupid obviously if ur machine isnt doing the job go to the next step.
Well I bought a counterfeit pen from staples and checked all 9 of my $20 bills all came out clean. Def not happy about how they were.
