Do I smell like a criminal??

So for those of you who have not heard the story let me take you back to last fall. I was in a hurry on my way to math class but realized I was very low on gas so decided to stop and fill up. I pulled to a pump next to a police officer. The moment I stepped out of my car the dog went wild. He looked so ferocious, I seriously thought he was going to bust out of the back seat and eat me. I had cash so I headed inside to prepay. As I reached the door I heard the dog go silent. I put $20 on pump 4 and hurried out. The second I caught the dog's eye all hell broke lose again. I was so taken back that I got in my car and drove away. My heart was pounding out of my chest but I was happy to be away from... lets call him Cujo lol. Just as I got to my exit my gas light came on. I started crying. I forgot to get gas! I went in to math class late and  with puffy eyes. Crunching numbers managed relaxed me and after class I went back to the gas station and explained to the man what happen. I charmed him, we laughed about it, and he let me get my gas.
Today I was on my way home from Chemistry, low on gas... Dun dun dun... I have class in the morning and am always running late so I stopped at Speedway even though I was eager to get home to my family. I again had cash so I went inside to pay. The same man was inside we had small talk and laughed it was obvious he remembered my space cadet moment. I went back to my car and saw a cop at the pump next to me. GRGGRRR BARK BARK BARK!! It was Cujo's coworker and he hated me too. This time the police officer talked to the dog and got him calmed down enough that I was not in fear of my life. And this time I held it together and pumped my gas.
I cant help but wonder "What the heck??". Do I smell like a criminal? On both occasions several other people were around and had no problem. Why did they hate me so much? I don't smoke pot or do anything else illegal so he didn't smell drugs... Oh well I guess I have an intimidating scent. This time I won though! I got my gas the first time, take that Cujo. lol
