so I work at a gas station and there is this guy who comes in on my shift. he creeps me out bad. he used to buy a biscuit and drink and stand right by my register to eat and drink till it he was done. and he told me about his marital problems. and his erectile dysfunction. and his wife's friends genital piercing. and when he found out (through a coworker who should mind her own business) that I was pregnant he started asking if I was getting horny and if my nipples were sensitive. he always sits outside in his truck for sometimes hours. the entire front of our store is Windows and be parks right in the middle. today while I was making coffee I caught him staring at me. chin resting in his hand. elbow propped up on his open window. he didn't even look away when I caught him. this is a 60ish year old man. he creeps me out so bad I won't go outside the store till he leaves. am I being paranoid?
