Anyone else ever pay for gas and forget to pump it?

So on my way home from work i stopped at a mobil to get gas because i was almost out. Went in, grabbed a soda and put 20 bucks on pump 2. Went back out to my car, completely forgot about the gas, got in and drove home. Now i have probably less than a gallon in my tank and i feel incredibly stupid lol. Anyone else ever do this or something similarly absent minded? via /r/cars http://ift.tt/2sQOFtp
