Upon hearing a customer, Nich immediately scuttled out of the back room. "Gah, why didn't the buzzer go off? The buzzer is always supposed to go off!" He scurried past Father Mortain to examine the door, which seemed to have consumed the entirety of his attention. "Are you sure you opened the door emphatically enough?" He tested the door, giving it a gentle swing, and then a wide one seeing if there was any different. His ears twitched, listening for any buzz coming from the back room, but alas, nothing. "I swear if it's vandals again I'll..." Then he noticed that the attachment clip has simply come undone from the door. He cleared his throat, reattached it with a single, swift gesture, and relished in the sound of his delightful buzzer going off in the back room.

Finally, the priest had his attention. "My apologies, the last customer must have knocked it loose on his way out. But I assure you, my home security systems don't use this outdated model. Oh, my no! See how easily it came off? No good. Needs to be changed. I just haven't had the time to replace my own. Too busy developing new razor coils for... well, that's not important. A man of the cloth has no need for violent things. Though, far be it from me to judge if you do have a need for such things. Only the gods may judge." He gave a laugh and went to shake Mortain's hand, giving the priest a brief respite from his rapid-fire ramblings. 

"Ah, but where are my manners. Welcome Father..." He hesitated for a moment trying to remember the priest's name, but for the life of him he could only think of varying gear radii, so he just left it at, "Father! To what do I owe this honorable visit? Is the church in need of some updated security? Please don't tell me some vandal is prowling about sticking his hand in the donation box at night. Unthinkable! Unspeakable! But, I can lock up that box nice and tight for you if you like. Money goes in, and it only comes out when the Father comes with the key. I can even offer a clergy discount. 20% off the catalog price. Would you like to browse my catalog, or did you have something specific in mind?" 

The rat looked up at Father Mortain with an eager grin. It wasn't often that holy men visited his store, and if his insatiable curiosity wasn't already obvious, it would explain away some of his... enthusiasm.
