Liquor Store

I always feel weird when I go to a liquor store to buy alcohol. I am 28 years old and hardly ever get carded anymore but yet I get so nervous when I am inside. I feel like everyone is staring at me and that the camera's zoom in me. I am just waiting for a cop to pull me over on the way out ... think it is repressed feelings from my college days of trying to sneak alcohol?!?
