My religious freak was also a pervert, and this happened yesterday.
I work in a musical instrument store. We sell everything from keyboards to guitars, all of the drums from everywhere, and sheet music detailing how to play songs on random instruments. We are the go-to place for our city and if you can't find what you need on the first floor, try the second or third! (Don't worry, we have elevators for getting King Kong's Drum Set safely to the ground floor without risking the stairs, but after that, vehicle transportation is YOUR problem!)
Anyway, in comes Religious Freak Pervert, disgustingly well known in these here parts, and identified by wearing an I <3 Jesus hat. The boss refuses to ban him, because he's technically a customer. ('Technically' because he'll buy something as small and cheap as he can find as justification for being in the store in the first place.) Boss has been complained to several times by other employees. My biggest mistake was greeting him like a normal customer before I spotted the damn hat.
Me: "Hello! Welcome to blah-blah Music Store! What are you looking for today?"
Oh shit! It's RFP! Abort! Abort!
RFP immediately begins to preach to me. Even as my body freezes, my brain jumps straight into The Snark Zone to save my sanity.
Jesus is life! Jesus is light! (40 watt, 60 watt or 120 watt?) Jesus will save us all from our sins! Have you been saved yet? (Well I've got some Life Savers in my pocket so...) Give me your hand (fuck no, don't you touch me!) so I can call Jesus to you (calling collect or toll free?) so that he can reveal himself to you. Let Him come inside you (um, ew) and bless you with the holy milk of salvation! (Is that what they're calling it these days? Pffft!)
My professional smile is frozen on my face and after several unsuccessful attempts, I finally turn his attention to the fact that he's in a music store and there are things to purchase. That's whent he switch is flipped and he goes full pervert.
RFP: "So what instrument do you play? I bet you play the flute, right?"
Me: "Well no, actually, I play the bassoon."
RFP: *leers* "Oh, so like, a bigger instrument than a flute, huh? You like big things?"
RFP: "Yeah, a bigger, longer, thicker version of the flute. Little girl like you can handle big things?"
Me: (I give him a scathingly disgusted look.) "Sir, this topic is NOT acceptable or appropriate. Leave the store now, or I'm calling the cops."
RFP: "Hey! Hey! I'm a customer! Look, I'll buy this!" He grabs for some random thing off a spinning display.
Me: "No. I'm refusing you service. Put it down and get out."
RFP pulls out his wallet, "Look! I have money, see? Cash!"
I'm walking away from him. I grab the phone off the hook, "OUT! OH YOU TEE! OUT!"
The boss comes out of the back office, sees and hears me yelling at the "customer" and starts running towards me, trying to sweet talk and smooth things over.
Nope! I talk over the boss at full volume.
Me: "I WILL NOT BE SEXUALLY HARASSED IN MY WORKPLACE!"
RFP runs out the door as I reach over and start to dial.
I make sure he's gone then put the phone down.
Me to boss: "Ban him, because if I see him in here again, I'm calling the police with or without your permission."
Boss just stared at me for a long time, then quietly walked into the back again.
I looked up corporate's number and put in a call that said my manager was allowing customer to sexually harass us. I live in faint hope that they'll handle this properly.
