I had Frappes with him one afternoon and chit-chatted for a bit. He was nice, like a grandfather figure, then he asked me while slowly massaging my shoulders, to come back around 12 (midnight) when he closes up shop and the two of us could go out for some drinks. Unfortunately I had "plans", but I just can't imagine how that night would have played out.
Oh he also spanked me as I walked past the store one day. Needless to say I found a new route back to my apartment center, which didn't involve walking past his shop.
