Shell

I was there today around 6:20 pm to buy Gas I went inside to pay there was nobody inside,I saw one car was circling in the parking lot that was she, came out from the car light up her Cigarette half way finished she came inside store ,I Greeted her and asked her her pump #3 full please She refused to sell the Gas to me because I had $100 Dollars Bill I told her it will be $35 Dollars or more. She replied I ran out my change You are the 7th person with $100 Dollars Bill. Next Gas Station I filled my tank actually it cost me $36.00 Dollars. Now It is my Curiosity,How come she couldn't make $36.00 Dollars sales to break a $100 Dollars or she didn't want to because she couldn't finish her Cigarette.
