Joseph Sobolewski saw a sign in a convenience store advertising two 20-ounce Mountain Dew bottles for $3. Sobolewksi only wanted one bottle, so he grabbed it, threw down two $1 bills — thinking he’d left a tip — and walked out of the store. Now he’s facing 7 years in prison over it. Sobolewski didn’t realize the sale price only applied to the two-bottle deal, instead of leaving a tip like he thought, he was actually short. A single bottle costs $2.29 and with tax , he was $0.43 short. Instead of simply chalking it up to a harmless mistake, the store called the police — over 43 cents.
