Check-out Computer Hates Bowie :(

I went to Walmart today to get the Best of Bowie CD that I've been wanting and i find it [oddly enough it was NOT in the David Bowie section, it was the last copy hidden behind Velvet Revolver] and I go to the self check out and i ring it up and an "approval needed" message popped up. so the lady came over and punched in the code and left. I hit "Finish and Pay" and it came up with a NEW approval needed message. and in waiting for help a message saying that there was a second object in bag area. finally after 20 minuets i get help. I pull out my money and the computer wouldn't take it! It seems like the computer just didn't want me to have my David Bowie CD! and so the lady came over again and said "David Bowie is great! let her pay for it!" and she hit the computer and punched in a code and then after a bit longer of it spitting my money out at me, it took it. THEN my change got stuck! yeah... that was a bit odd lol. but i have my Bowie and am listening to it now lol
