Chevron Yelm

I am from oregon. I was visiting the area when I stopped in for gas. I went in and told the young man that I wanted a fill up on pump 3 and gave him $40.00 to start pump as my boyfriend was at car. I then told the young man I was going to get a beverage and would be right back. Mind you no one else in store but this clerk and another male employee who did not stay behind counter. When I came back to counter with 2 / 20oz bottles of glaceau water and a 20oz new flavor of sprite the young man totaled these on till and told me that would be $8.and some change. I laughed and looked at dark hair boy and said i just gave you $40 on pump 3. He said no mam you did not. I proceeded to look out side at pump 3 and my man had not started to pump as the kid had not turned on pump for him. The dark haired kid I think thought I was alone and then changed his tune and turned on pump 3. The young man started making excuses about the money. I looked at him and said there is no way my 2003 Honda CRV is going to take $40.00 to fill up. The total on gas was $29.75. The young man added the 3 beverages again and gave me back .85cents. I told him that was not correct change. His excuse before was that people come in all the time and give money to prepay for gas and never come back for there change. He stated he has been given $40. On a $17. Fill up and customer never came in for change. The young man looked at receipt that I asked for and said oh I do owe you more and opened till and gave me a $1. I went to my car and told my boyfriend about the experience and he couldn't believe it. I still have receipt for total purchase and I did discover when looking at it earlier that the dark hair boy did indeed succeed in ripping me off on beverages. I did not buy a 12 pack of pop for $4.99 young man. You are a thief and I have proof by receipt as well as the 3 empty beverage containers with bar codes on them. Why did you feel the need to steal from me? Because I am a woman, you thought I was alone, because you saw my oregon plates on my car, just someone passing through??? WELL young man, it just so happens I have family in that area that I was visiting. I also have family that own and operate chevron stations. YOUNG MAN YOU NEED TO LEARN NOW AT A YOUNG AGE THIS IS THEFT AND YOU WILL BE HELD ACCOUNTABLE NO MATTER WHAT THE MONETARY AMOUNT WAS. I will make sure of this!!!! As far as chevron goes I will hold you accountable as well this should never happen to anyone traveling or local. He is an employee of yours. You have cameras set to protect yourselves from theives, they should also be set to protect your customers. I am curious as how long this dark hair young man has been doing this side work at this chevron. How long and how many people???? How did he add a 12 pack of pop on my tab when there was not a 12 pack any where need register that I saw. How is he deceiving not only customers but his employer as well. I work with public and I had a woman co-worker whom thought she could get away with this same crime. She got caught and spent 18 months in prison. In my opinion it was not nearly enough time served because she targeted a lot of our elderly and lonely men clientel. VERY DISAPPOINTED CUSTOMER!!
