What's the creepiest/ perverted thing a customer has said to you?

I have a lot of stories but this one comes to mind. I am a 36f working in a grocery store. About 4 years ago, I was kneeling stocking the meat counter and I guess my underwear was showing a bit. Later I had to go on register and a much older man comes up to my lane and asks if he can give me a compliment. I say sure thinking is would be about customer service or something and he proceeds to tell me that he loved the way my underwear was sticking out of my pants and it looked so good against my complexion. I started wearing high-waisted pants from then on.
