Two thoughts: 1) Old whataburger bags/packaging don't smell too well after a couple of days since the paper they put around the burgers soaks up all the grease and such. Imagine if she got the chicken fingers and there were old containers of white gravy in those bags...The old pizza boxes probably smell pretty bad too. 2) Why not just use all the cups she has laying around as ashtrays? It seems like she has enough.
1) I'm just surprised anyone has enough room left in their arteries to sustain life after that much Whataburger. 2) Why mess up a cup when there's a perfectly good computer sitting right there?
